Invitation Letter for Vietnam Visa: Complete Guide to Sponsorship, Requirements & Application Process

Vietnam has become one of Asia’s most attractive destinations for tourism, business, investment, and international cooperation. Every year, millions of foreign travelers visit Vietnam for holidays, business meetings, trade activities, employment opportunities, and family visits.

While Vietnam’s electronic visa (E-Visa) system has simplified entry procedures for many nationalities, certain visa categories and specific immigration situations still require an Invitation Letter or Sponsorship Letter issued by a Vietnamese organization, company, or individual.

Understanding when an invitation letter is required and how it works can help travelers avoid delays, visa refusals, and unnecessary complications before their trip.
