Tại sao đơn xin eVisa Campuchia bị từ chối (và cách người Mỹ tránh điều đó)

Cause #2: the name does not match your passport exactly

The second-biggest cause of flagged US applications is a name that does not match the passport machine-readable zone — the two lines of text and < characters at the bottom of your bio page. Cambodian Immigration parses that zone character for character. If the name you typed into the application does not line up with it precisely, the file gets held for a correction.

The usual culprits are small. A dropped middle name when your passport carries one. A married name typed into the application when your passport still shows your maiden name. A hyphenated surname entered without the hyphen, or a Jr / Sr / III suffix added or omitted. Americans also sometimes enter the name as it appears on a driver license, which can differ from the passport — the passport is the only document that matters here.

The rule is simple: type your name exactly as it appears in the machine-readable zone, including every middle name and every suffix, and nothing that is not there. If you married recently and your passport still shows your maiden name, apply in your maiden name and travel on that passport. If you have already updated the passport, apply in the new name. Never mix the two, and never "correct" your name to the version you prefer — match the book.

Name mismatches are common enough that we wrote a dedicated walkthrough for them. If your file was held over a name field, our guide to passport name mismatches for US citizens covers married names, middle names, suffixes, and the exact way to read your own machine-readable zone so the resubmission clears.

Cause #3: an unreadable passport bio-page scan

Cambodian Immigration has to read every detail on your passport bio page — name, passport number, date of birth, issue and expiry dates, and the machine-readable zone. If the scan you uploaded is blurry, washed out by flash, or missing a corner, the validator cannot confirm the data against what you typed, and the file gets flagged for a clean re-upload.

• Glare from flash. The laminate bounces a camera flash straight back and blows out the page. Use daylight from a side window instead, never the flash.
• A cropped corner. The most common scan rejection is one corner of the bio page sitting outside the frame. Leave a thumb-width of margin on all four sides.
• Blur or low focus. Tap to focus on the text before you shoot, and hold the phone steady and parallel to the page.
• A busy background. Put the passport on a plain, dark, flat surface — a wooden desk or a dark notebook — so the page edges read clearly for the validator.

You do not need a flatbed scanner. A phone-camera photo is fine when the whole page is in frame, the text is sharp, and there is no glare. Before you upload, check that you can read every letter of your name, every digit of the passport number, and the two lines of < character codes at the bottom. If any of that is fuzzy, retake it. A clean scan is the difference between an instant pass and a day lost to a correction.

Cause #4: mistyped data and a short-dated passport

After the photo, the name, and the scan, the remaining flags fall into two buckets: typos in the data you entered, and a passport that does not meet the validity rule. Both are quick to check before you submit, and both are avoidable.

On the data side, the usual slips are a transposed digit in the passport number, a date of birth entered in the wrong format, or an expiry date that does not match the book. The validator cross-checks these against your uploaded scan, so any mismatch holds the file. The fix is to read each field back off the passport itself before you hit submit — not from memory, and not from another document. Pay particular attention to the passport number, where a single wrong character is enough to trip the check.

On the validity side, your US passport needs at least 6 months of validity from your planned date of entry into Cambodia, plus one full blank page for the entry stamp. A passport inside that 6-month window will get you stopped — and in practice the airline often catches it at your US departure gate before Cambodia ever sees the application. If you are anywhere near the line, renew first. Standard US passport renewal runs about 4 to 6 weeks in 2026, with expedited service roughly 2 to 3 weeks, so build that into your timing.

If you want the full set of inputs the form asks for, laid out so you can check each one before submitting, our Cambodia eVisa documents required for Americans guide lists the five items and what each must look like. Confirming the data against that checklist is the most reliable way to clear the validator on the first pass.

What to do when your file is flagged (and what it costs)

Here is the part most Americans worry about and almost never need to: a flagged file is not a forfeited fee. When Immigration asks for a correction, you get a clear email saying exactly what to fix — usually a fresh photo, a corrected name field, or a cleaner scan. You re-upload the fix at no extra charge, and the 3-business-day clock keeps running rather than resetting from zero. Free resubmission is part of the all-in price, so you are never penalized for needing a second go at the upload.

The thing that does slow people down is not reading the correction request closely. The email tells you which field or document failed; fix that one thing rather than redoing the whole application. Replying quickly is what keeps the timeline tight — the longer a flagged file sits, the closer it drifts to your travel date. Most corrections clear on the first resubmission once you know the specific cause, which is the entire point of ranking the causes the way this guide does.

In the rare case where a file truly cannot be approved — a passport too short-dated to use at all, for example — that is a different conversation from a routine flag, and our note on refunds for rejected US applications explains where you stand. For the ordinary case, though, a flag is a fix, not a refund question.

Clear the validator on the first try

Almost every Cambodia eVisa flag for Americans comes down to four things: the photo, the name, the scan, and a typo or short-dated passport. Get those right before you submit and you clear the validator on the first pass — Tourist eVisa $80 USD, Business eVisa $90 USD, approved in 3–5 days, delivered as a printable PDF by email. The few minutes you spend checking the photo against a white wall and reading your name off the machine-readable zone are the cheapest insurance there is against losing a day to a correction.

One reminder before you start. The visa is one form, the e-Arrival Card is a different form, and both are mandatory for every air arrival in 2026. The visa application happens now; the e-Arrival happens within 7 days before you fly, and its passport details have to match the eVisa exactly — a mismatch there is its own common reason Americans get held up at the kiosk. Plan for both at the start and neither one surprises you.

Next steps and related reading for Americans: apply for your Cambodia eVisa once your photo, name, and scan are clean, read the photo requirements for Americans before you upload the headshot, check the documents required for Americans so every field matches your passport, and bookmark our Cambodia visa for United States citizens hub as the single canonical reference.
