Thanks for your concern,
For your first entry:
Vietnam offers 15-day visa exemptions with single entry for visitors from the U.K.. However, their
passports should have at least six months of validity upon the date of arrival to meet airlines’
requirements, and their arrival date is NOT within 30 days from their last exit date with visa exemption.
