The Laos LDIF digital arrival form, explained

Last updated: October 30, 2026 · By Wander Cambodia

Travellers combining Laos with Cambodia — a very common loop, including through the Tropaeng Kreal crossing we walk through in our Laos–Cambodia border guide — now meet digital arrival forms on both sides of the trip. Cambodia's has existed since July 2024; Laos's LDIF is the newer one, and it is the one people are still being surprised by. Here is what is confirmed about it, kept deliberately to what is verified.

What the LDIF is — and is not

The LDIF (Laos Digital Immigration Form) replaces the paper arrival card at the checkpoints where it applies. It is an arrival record, not a visa, not a fee-bearing permit, and not optional where it is in force. It does not change who needs a visa for Laos or what the visa costs: visa on arrival still runs about $40 in cash for most nationalities (the range is roughly $30–50 depending on nationality — and bring clean, pristine US dollar bills, because damaged notes are a classic refusal point), and the official Laos eVisa at laoevisa.gov.la runs about $45–50.

Where it applies — and the eVisa checkpoint trap

The LDIF has been mandatory since September 1, 2025 at the main international airports and at the First Thai–Lao Friendship Bridge (Vientiane–Nong Khai). Roll-out beyond those points has been phased, so the honest advice for smaller crossings is to expect either the digital form or the paper card and be ready for both. The related trap is on the visa side: a Laos eVisa is accepted at only 9 of the country's 33 checkpoints — mostly the big airports and the main bridges, and not most overland crossings from Vietnam. If your route enters Laos somewhere small, visa on arrival or a consulate visa is usually the workable route, and the entry point decides which. Cambodia has a mirror-image version of this trap: its eVisa works at only 5 entry points, listed in our Cambodia eVisa guide.

Doing both countries on one trip

File each country's form separately, in its own window, on its own official system. For Cambodia, the e-Arrival card is free, mandatory for air arrivals, and is completed within 7 days before you land, producing a QR code; land and sea arrivals into Cambodia still use paper. Coming the other way — Cambodia into Laos at Tropaeng Kreal — you are at a small land crossing: carry pristine cash dollars for the Laos visa fee, and do not assume either country's digital form covers the other side. And one routing fact that shapes the whole loop right now: the Thailand–Cambodia land borders remain closed (since June 2025), so an overland Laos loop cannot exit into Thailand and drop down into Cambodia overland — the status page is here. Land with working data for form-filing at borders: our eSIM vs local SIM guide covers the Cambodia side of that choice.

Frequently asked questions

Is the LDIF the same as a Laos visa?

No. The LDIF is the digital arrival record that replaces the paper card. You still need your entry permission separately — a visa on arrival (about $40 cash for most nationalities) or an eVisa (about $45–50).

Does the Cambodia e-Arrival card work for Laos, or the LDIF for Cambodia?

No. They are separate national systems. Cambodia's e-Arrival is free and mandatory for air arrivals into Cambodia; the LDIF is Laos's arrival form. File each one for the country you are entering.

Where has the LDIF been mandatory?

Since September 1, 2025, at the main international airports and the First Thai–Lao Friendship Bridge. Smaller crossings are phased — be ready for the paper card as a fallback.
