Applying in Hanoi (soft power):
If I arrive in Hanoi on the October 26th (Sunday), can I apply on that day or would I wait until Monday to submit the paperwork?
Does it matter that my booking reservation would show that I just arrived, and that I only have the reservation for 2 weeks?
Or do they not really scrutinize that part of the application?
Thanks in advance!
TLDR : Answer Summary
You can apply for your visa on the same day you arrive in Hanoi, and there is no need to wait until the next day. Many users have reported that they submitted their applications upon arrival, often submitting documentation such as boarding passes and accommodation receipts, which were accepted without issue. It is advisable to prepare your online application before arrival and add required documents later. A two-week booking reservation is sufficient, but it's recommended to apply for a longer visa (four weeks) to allow for any unexpected delays.
