scheduling interview blocks in Vietnam

[BigMike93ATX 2]

this only applies to K1 visa applicants in Vietnam. my question is. when you go onto the account to schedule an interview. there was only a few days in march that were available for interviews. but the rest of the months like, April, May, June etc. were grayed out. does that mean those dates were already booked for interviews? or does it work by monthly basis, as in, at the beginning of each month. those dates will be available for booking interviews only for that current month? please if anyone can tell me it would be much appreciated. thank you.

From what I remember, you can only see what is available. Not sure how far out they go. My fiance kept checking the calendar and was able to grab a date close to the time we wanted. When we first looked, it was gray and not available. She kept checking and got it. If someone cancels - or something opens up - you can get it. Keep checking (several times a day) and see if something becomes available. Keep checking - that's my advice.
