अमेरिकी यात्रियों को कंबोडिया ई-वीजा के लिए कितने समय पहले आवेदन करना चाहिए?

The short answer, and why timing has two edges

So the right window is a band, not a deadline. Wide enough to absorb a weekend, a Cambodian public holiday, or a flagged photo. Narrow enough that your 3-month validity is not burning down while you wait to travel. The rest of this guide does the math for that band, then shows you where the e-Arrival Card fits, what changes around holidays, and when you can safely cut it close. If you are ready now, you can apply in about ten minutes, and our Cambodia eVisa processing time guide for Americans covers the 3-business-day approval in detail.

The 2-to-4-week sweet spot, step by step

Why not five or six weeks, to be extra safe? Because of the validity ceiling, which the next section covers in full. For a quick gut check on the rest of the application, our step-by-step Cambodia eVisa guide for Americans walks through every form field, so you know the whole thing genuinely takes about ten minutes once your photo and passport scan are ready.

The early edge: do not let your eVisa expire on the shelf

Weekends, Cambodian holidays, and US holidays

Cambodia observes a longer list of public holidays than the US, and several of them run multiple days. Khmer New Year in mid-April, Pchum Ben in late September or early October, and the November Water Festival are the big multi-day stretches. If your application lands right before one of those, your 3 business days can stretch across a full calendar week. Our guide to how Cambodian weekends and holidays affect processing for Americans maps the dates worth planning around.

The practical move is to submit early in your week rather than late, and to add an extra buffer day or two if your application window overlaps a major Cambodian holiday. If you are traveling during one of the big festival periods, our guide to Cambodia visa processing during the holiday season for Americans is worth a read before you lock your timing in.

The late edge — and where the e-Arrival Card fits

There is no extra charge to fix a flagged file, and the 3-business-day clock keeps running once you re-upload — but the correction still needs Cambodian business hours to clear, and you cannot manufacture more of those at midnight before a 6 a.m. flight. If you genuinely have only days, do not panic, but do read our realistic last-minute Cambodia visa timeline for US citizens so you know exactly what is and is not possible on a tight clock.

Timing by scenario: when your dates are firm, soft, or imminent

Putting your timeline together

Here is the whole countdown in one line. Around 2 to 4 weeks before you fly, apply for your eVisa — Tourist $80 USD, Business $90 USD, both approved in 3 business days and delivered as a printable PDF by email, both with free resubmission if Immigration flags a correction and US-timezone support behind them. Then, in the final 7 days, file your e-Arrival Card. That is the entire timeline. If you want the deeper version of the approval math, our guide to how long the Cambodia eVisa takes for Americans breaks down the 3-business-day clock.

A few related decisions worth settling at the same time you pick your application date. If you are still figuring out the best day and hour of the week to submit, our note on when to apply for the best Cambodia eVisa timing for US citizens covers the time-zone edge in detail. And if your departure is genuinely close, do not guess — the last-minute timeline guide for US citizens spells out what a tight clock actually allows.
