For travelers from the United States, Cambodia offers a mesmerizing journey into the heart of Southeast Asia. From the awe-inspiring sunrise over Angkor Wat to the somber history of the Killing Fields and the pristine beaches of Koh Rong, the Kingdom of Wonder is a top destination for American adventurers.

Whether you are flying out of LAX, JFK, or connecting through major Asian hubs like Bangkok or Singapore, getting your travel documentation sorted is the first step. Fortunately, the process for US citizens is straightforward. You can bypass the embassy in Washington, D.C., and apply entirely online using the Cambodia eVisa system.
This guide answers every question you might have about applying for a Cambodia eVisa for US citizens, ensuring your trip is smooth and hassle-free.
Do United States citizens need a visa for Cambodia?
Yes. United States citizens are required to hold a valid visa to enter the Kingdom of Cambodia. The US is not on the visa-exemption list.
However, the process is incredibly convenient. You do not need to mail your physical passport to an embassy. US passport holders are fully eligible for the Electronic Visa (eVisa), which allows you to complete the application online and receive your travel authorization via email.
How to get a visa for Cambodia from the USA?
There are three main ways for US citizens to obtain a visa:
- Online (eVisa): The most recommended method. You apply online, pay with a credit card, and print your visa. It saves time and guarantees entry approval before you fly.
- Visa on Arrival (VOA): You can apply upon landing at major airports. This requires standing in line, filling out paper forms, and paying in cash (USD).
- Embassy Visa: You can visit the Royal Embassy of Cambodia in Washington, D.C., or a consulate. This is typically only necessary for specialized long-term visas not available online.
What are the requirements for a Cambodian tourist visa for US citizens?

To apply for Cambodia eVisa application successfully, you need:
- Valid Passport: Your US passport must be valid for at least 6 months beyond your date of entry.
- Digital Photo: A recent passport-style photo (specifications below).
- Credit/Debit Card: Visa, Mastercard, American Express, or Discover to pay the online fee.
- Email Address: To receive the PDF visa approval.
How long is the tourist visa valid for Cambodia?
- Validity (Entry Window): The eVisa is valid for 90 days from the date of issuance. You must enter Cambodia within this 3-month window.
- Duration of Stay: Once you enter, you are permitted to stay for 30 days.
- Extension: If you love it there, you can extend your Tourist (T) visa once for an additional 30 days at the Immigration Department in Phnom Penh.
What's the processing time for a Cambodian visa application?
- Standard Processing: Typically takes 3 to 5 business days.
- Rush Processing: Available for an extra fee, often delivering results in 2 to 3 days.
- Super Rush: Can sometimes be processed in 24 hours for urgent travel.
- Tip: We recommend applying at least one week before your flight to account for any system maintenance or holidays.
What are the photo requirements for the Cambodian e-Visa?

The digital photo you upload must meet these standards to avoid rejection:
- Format: JPG, PNG, or BMP.
- Size: Under 2MB.
- Style: Color photo with a plain white or off-white background.
- Expression: Neutral face, eyes open, no glasses.
- Recency: Taken within the last 6 months.
What Cambodian airports offer visas on arrival?
If you choose not to get an eVisa, you can get a Visa on Arrival at:
- Phnom Penh International Airport (PNH/KTI)
- Siem Reap Angkor International Airport (SAI)
- Sihanoukville International Airport (KOS)
Note: Be prepared for potential queues, especially if a large flight from the US or Europe lands just before you.
Can a US citizen with a tourist e-visa enter Cambodia by land from Thailand?
Yes, but only at specific checkpoints.
- Poipet (Banteay Meanchey): The busiest crossing, connecting Aranyaprathet (Thailand) to Siem Reap.
- Cham Yeam (Koh Kong): Connects Hat Lek (Thailand) to the coastal areas.
- Warning: Some smaller, remote crossings may not have eVisa scanners. If you plan to cross at a minor border point, you may be forced to buy a Visa on Arrival. Stick to the major crossings listed above to use your eVisa.
Are there ATMs at Cambodian airports for US dollars?

Yes. Cambodia operates on a dual-currency system (Cambodian Riel and US Dollars).
- Dispensing: Most ATMs in airports and major cities (Phnom Penh, Siem Reap) dispense US Dollars and sometimes Riel.
- Fees: Be aware that Cambodian ATMs charge a fee for foreign cards (often $4 - $6 USD per transaction) on top of what your US bank charges.
- Condition: Ensure your US bills are crisp and untorn. Old, ripped, or stained bills are often rejected by shops and hotels.
What are common challenges travelers face with Cambodian e-visas?
- Land Border Scams: If crossing from Thailand (Poipet) by bus, "fixers" may try to trick you into paying for a "fake" visa or "stamping fee" before you reach the real border. Tip: Ignore them, walk straight to the official immigration building, and present your printed eVisa.
- Photo Rejection: Uploading a low-quality selfie often leads to "Pending" status or rejection.
- Wrong Entry Date: If your travel plans shift significantly outside the 90-day validity window, your visa becomes void.
Should You Apply for an e-Visa Through an Agent or the Government Website?
- Government Site: Cheaper, but offers zero support. If the site crashes or your photo is rejected, you are on your own, and fees are non-refundable.
- Visa Agent (e.g., e-visa-cambodia.com):
- Pros: We review your application manually to prevent rejection. We resize your photos to meet government specs. We offer 24/7 support via chat/email if you are confused or need an urgent status update.
- Cons: Small service fee.
- Verdict: For US travelers who value peace of mind and want to avoid the bureaucratic hassle or risk of rejection, using a trusted agent is often worth the small extra cost.
