The Vietnam entry approval letter is an official document issued by Vietnam’s Immigration Department, serving as pre-authorization for foreigners to enter the country. This critical document contains essential information, including sponsor details, applicant information, entry purpose, stay duration, and designated entry points. Without this approval letter, foreign nationals cannot proceed with obtaining their actual visa.
The application process involves document preparation, submission through a Vietnamese sponsor, processing by immigration authorities (typically 3-5 working days) and verification of results online. Let’s explore each aspect in detail to ensure your Vietnam entry goes smoothly.
What is a Vietnam visa entry approval letter?
A Vietnam approval letter (visa permission letter) is an official document issued by the Vietnam Immigration Department that authorizes foreigners to enter Vietnam for various purposes such as tourism, business, investment, work, or family visits. This document, sometimes referred to as a Vietnam invitation letter, contains important information including:
- Personal details: full name, date of birth, nationality of the foreigner
- Sponsoring organization: name and address of the Vietnamese organization sponsoring the foreigner
- Entry duration: the permitted period for entry into Vietnam
- Visa collection location: Vietnamese Embassy/Consulate abroad or international airports in Vietnam
Currently, the Vietnamese government requires all approval letter applications to be submitted online. Therefore, visa permission letters now have digital stamps rather than physical red stamps.
Important note: A Vietnam invitation letter is NOT a visa. To obtain an entry visa for Vietnam, foreigners must present this approval letter (photocopy) at either a Vietnamese Embassy/Consulate abroad or at a Vietnam border checkpoint to receive their visa.

Types of Vietnam visa entry approval letters
Vietnam approval letters are classified into two main categories:
Based on entry purpose:
- Tourist approval letter – ideal for those applying for a Vietnam tourist visa application
- Business/work approval letter – required for Vietnam business visa or Vietnam investors visa
- Relative visit approval letter – necessary for family reunions or visits
Based on visa collection location:
- Airport visa approval letter (visa on arrival)
- Embassy/Consulate approval letter
Each type of Vietnam invitation letter serves different needs and follows specific application procedures, so identifying the correct type for your situation is essential for a successful application.

How long is a Vietnam visa entry approval letter valid?
The validity period of a Vietnam visa permission letter depends on the purpose of entry:
- Business/work purpose: Maximum 1 year with a work permit; maximum 90 days without a work permit
- Relative visit/tourism purpose: 3 months to 1 year depending on the sponsor’s documentation
This validity refers to how long you can stay in Vietnam, not when you must enter. You should plan your entry according to the dates specified in your Vietnam invitation letter.
For those seeking longer stays for work-related purposes, understanding the Vietnam work visa cost is essential for proper budgeting and planning.
