Thanks for your question. We are glad to answer that everybody who has approval letter instead of an official visa delivered by embassy enter Vietnam legally. However it's difficult for Vietnam Visa online agents to process approval letter for some nationalities. We hope that our information is helpful to you. Vietnam Visa Team
