Flying into Kathmandu, the queue at Tribhuvan Airport's visa-on-arrival counters moves slowly. Travelers shuffle forward, clutching passports and forms, only to be sent back for a missing photo or the wrong cash. The process looks straightforward on paper, but small errors cost time and money. Here's what goes wrong and how to sidestep the traps.

The Photo That Trips Up Arrivals at Tribhuvan

Nepal's visa-on-arrival requires two passport-size photos. Many travelers assume a digital copy on their phone will suffice. It will not. The immigration officer needs a physical print, and the counter staff will not accept a screen. Without a photo, the applicant is directed back to the queue or sent outside the terminal.

There is no photo booth inside the arrivals hall. A small kiosk operates just outside the terminal building, but it is easy to miss in the chaos of arriving passengers and taxi drivers. The kiosk charges around 100 to 200 Nepali rupees per print, which is reasonable, but it means leaving the line and starting over.

Some travelers carry a photo from a previous trip that is more than six months old. Officers occasionally reject these if the person's appearance has changed significantly. It is safer to bring fresh prints. Glossy paper with a white background is standard, and two copies per traveler are the minimum.

Packing photos in a carry-on bag, not checked luggage, is a simple precaution. Also keep a photocopy of the passport data page. Local print shops near the airport can make copies, but during peak hours the queue for the kiosk can add 20 to 30 minutes to the process.

A traveler from Singapore, for instance, once arrived with a single photo that was three years old and showing a beard he no longer had. The officer sent him back. He spent 25 minutes at the kiosk, then rejoined the queue behind 40 people. His group had already cleared immigration and was waiting at the baggage claim. The lesson: bring two fresh photos per person, and check that they resemble your current appearance.

Why the USD Bill Requirement Still Catches People

Nepal's visa fee is payable only in US dollars cash. ATMs at Tribhuvan dispense Nepali rupees, not dollars. Exchange counters inside the airport offer poor rates, sometimes 10–15 percent below market, and they may not have enough small bills. Travelers arriving with euros, pounds, or other currencies must exchange first, losing value on the conversion.

The fee schedule as of late 2024 is roughly: 15 days – US$30, 30 days – US$50, 90 days – US$125. Exact change speeds processing, but officers generally accept slightly larger bills and return change in Nepali rupees. The change may come in wrinkled notes that local shops later refuse, so checking the bills before leaving the counter is wise.

A common workaround is to carry US dollars from home. Even crisp, unfolded bills are preferred. Some travelers report being asked for newer series notes (post-2009), though this is not an official rule. If stuck without dollars, a traveler can use a credit card at the bank counter before immigration, but that adds another queue and a service fee of around 3 percent.

For those transiting through a hub like Bangkok or Dubai, exchanging a small amount of local currency for US dollars before departure avoids the airport markup. It is one less variable to manage after a long flight.

There is a trade-off here: carrying a large amount of USD cash for a 90-day visa (US$125) plus extra for extensions or multiple entries means carrying perhaps US$200–300 in cash. Some travelers prefer to rely on ATMs in Kathmandu, but those dispense Nepali rupees, which cannot be used for the visa fee. The counter argument is that many hotels in Thamel accept USD for payment, so the cash is not wasted. But if you plan to pay for the visa with a card, be prepared for the additional queue and fee. A traveler from Germany once tried to pay with a 50-euro note; the exchange counter gave him only US$48 after fees, and he was short US$2 for the 15-day visa. He had to exchange more, losing another 10 percent. Better to arrive with exact USD in small denominations.

The Online Form Everyone Fills Wrong

Nepal's online visa application system, available on the Department of Immigration website, lets travelers pre-fill their details. But the form has traps. The departure card and visa application are separate documents. Some travelers fill only the departure card and then queue for a paper visa form, wasting time.

A recurring error is the 'previous visa' field. If the traveler has held a Nepali visa before, they must check 'yes' and provide the old visa number. Leaving it blank can trigger a manual review, holding up the line. The hotel address field must match the booking confirmation exactly. A misspelled hotel name or missing street number raises questions.

The passport number field is case-sensitive in the system. Entering all lowercase when the system expects uppercase can cause a mismatch. Double-checking the spelling before submission saves trouble. The form also asks for a local contact; listing the hotel's phone number is standard, but some travelers put their own mobile, which may not work on arrival.

After submission, the system generates a barcode. Printing this barcode and carrying it is essential. Without it, the officer must manually enter the data, which takes longer. The online form is not mandatory — paper forms are available — but using it cuts the counter time by roughly half.

Another common mistake: travelers fill the form on a phone and then cannot find the barcode email. The system sends a confirmation with a barcode attachment, but spam filters sometimes catch it. Checking the spam folder before departure is a simple step. One traveler from Australia filled the form at a cafe in Bangkok, but the email went to junk. He arrived at Tribhuvan without the barcode and had to fill a paper form, adding 15 minutes. The paper form itself has its own traps: it asks for father's name, mother's name, and occupation, fields that the online form skips. Travelers who switch mid-process may be caught off guard.

How Multiple-Entry Misunderstandings Cost Time

The default visa issued on arrival is single-entry. Travelers who plan to leave Nepal and return — for a side trip to India or Bhutan, for example — must request a multiple-entry visa at the counter. The online form does not have a clear option for this; the request is made verbally to the officer.

Proof of onward travel is required for multiple-entry visas. A flight booking out of Nepal and back into the country satisfies this. Overland exits, such as crossing into India at Sunauli or Birgunj, require a separate re-entry visa if the traveler plans to return the same way. The visa-on-arrival is only valid for entry by air.

A traveler who receives a single-entry visa and then leaves Nepal will need a new visa on return, paying the full fee again. Some try to extend their visa instead, but the extension office in Kathmandu has limited hours — open roughly 10 AM to 2 PM on weekdays — and the process takes at least a day.

For trekkers who plan to exit overland to Tibet (now closed to individual travelers) or to India, understanding the entry-exit rules saves money. The Department of Immigration's website lists the conditions, but the information is dense. Asking at the counter before paying is better than assuming.

Consider a traveler who books a 30-day trip that includes a four-day side trip to Varanasi, India. They arrive at Tribhuvan, get a single-entry visa without thinking, go to India, and then cannot re-enter Nepal without buying a new visa. The cost: another US$50 for a 30-day visa, plus the time at the counter again. If they had requested multiple-entry at the start, the fee would have been only slightly higher — the multiple-entry visa costs the same as single-entry for the same duration, but requires justification. The officer may ask for proof of the side trip. A printed flight booking or bus ticket suffices. Without it, the officer may deny the multiple-entry request and issue single-entry anyway. So carry those documents even if you are not asked.

The Visa Category Confusion at the Counter

Nepal issues different visa codes for tourism, trekking, mountaineering, business, and volunteering. A tourist visa allows sightseeing and short treks on established routes. A trekking visa is required for high-altitude treks that pass through restricted areas, such as the Upper Mustang or Manaslu region. The counter staff sometimes do not correct a traveler who selects the wrong category.

Mountaineering permits are separate from the visa. Even with a valid tourist visa, climbing peaks above 6,500 meters requires a permit from the Department of Tourism. Some travelers arrive with a trekking visa and assume it covers climbing, only to be denied at the permit office.

Volunteer work requires a different classification — a non-tourist visa with a recommendation letter from the sponsoring organization. Travelers who declare 'tourism' at the counter and then start volunteering risk being flagged for visa misuse. In practice, short-term volunteering (a few days) often goes unnoticed, but the rule exists.

Business visitors need an invitation letter from a Nepali company. Without it, the officer may issue a tourist visa, which does not permit business activities. The distinction matters for anyone attending meetings or conferences. The counter staff rarely ask the purpose in detail, but a random check can lead to denial of entry.

A traveler from the UK once arrived for a two-week volunteer teaching program. He declared tourism at the counter, got a tourist visa, and started teaching at a school in Pokhara. A routine check by immigration a week later found him in the classroom. He was fined and given 48 hours to leave the country. The sponsoring organization had failed to provide the recommendation letter. The lesson: if your activity is not pure tourism, get the correct visa category upfront. The extra paperwork is worth the peace of mind.

What Happens When the Visa Machine Crashes

Tribhuvan Airport's visa-on-arrival system runs on a network of computers and printers. Outages happen. During peak season in October and November, the system sometimes slows or crashes under load. Paper forms are accepted as backup, but the supply of forms runs out by mid-afternoon on busy days.

When the system goes down, queues stretch for hours. Staff ask for patience but offer no compensation or priority for delayed connections. Travelers with a connecting flight to Pokhara or Bharatpur may miss it. The airport has limited facilities — a few benches and a overpriced snack bar — so waiting is uncomfortable.

A temporary outage in 2023 lasted nearly three hours, according to news reports, stranding hundreds of passengers in the immigration hall. Those who had already filled paper forms were processed manually, but the pace was slow. Travelers arriving with all documents ready — photos, USD, printed barcode — moved through faster.

Carrying a backup plan helps. A printed copy of the online form, extra photos, and small USD bills for the visa fee reduce dependency on the system. Also note that the visa counter closes after the last flight arrives, but if a flight is delayed, staff may stay late. There is no guarantee.

During the 2023 outage, a traveler from Canada who had a connecting flight to Pokhara missed it because the system crashed just as he reached the counter. He had to rebook for the next morning, costing him a night in Kathmandu and a US$50 change fee. His friend, who had filled a paper form at the seat on the plane, was processed manually and caught the flight. The difference: one piece of paper. It is worth picking up a paper form from the counter even if you have an online barcode, just in case.

Packing a Photo Saves an Hour at Immigration

The single most common delay at Tribhuvan is the missing passport photo. Travelers who pack two fresh prints per person in their carry-on skip the kiosk queue entirely. The photo must be 35 mm by 45 mm, white background, glossy finish, and no older than six months. Digital prints from a home printer sometimes work but may be rejected if the quality is poor.

Local shops near the airport charge around 100 to 200 NPR per print. That is cheap, but the time cost is higher — 15 to 30 minutes out of the queue. During peak hours, the kiosk itself has a line. Travelers who arrive with photos already in hand can head straight to the counter.

Also carry a photocopy of the passport data page. This is not officially required for the visa, but it is useful for filling out hotel registration forms or if the passport is temporarily taken for processing. Some hotels in Kathmandu ask for a copy at check-in.

For families, each member needs their own photo and form. Infants are not exempt. A parent who forgets the baby's photo will be sent back. Packing a small envelope with all documents per person, labeled, keeps things organized. It is a small habit that cuts the arrival chaos by half.

There is a counter-argument: some travelers argue that the kiosk is fast enough and that carrying extra photos is unnecessary. But the data from frequent flyer forums suggests that during peak months (October–November, March–April), the kiosk queue can exceed 30 minutes. A traveler who arrives on a late-night flight with few other passengers might breeze through without photos, but that is the exception, not the rule. The prudent choice is to bring photos.

The visa-on-arrival system at Tribhuvan is workable, but it punishes the unprepared. A few minutes of planning before the trip — fresh photos, crisp USD, a printed barcode — can save an hour or more in line. The airport's infrastructure is not built for large crowds, and the immigration officers have little patience for mistakes. Travelers who treat the process as a checklist, not a formality, move through faster. And those who do not? They learn the hard way, re-queuing with a photocopy from the kiosk while their friends already have their bags.
