Thank you for your answer. I also wanted to double-check a few questions because I read other forums in Visajourney but everyone gave different answers for it.
For the question do you have any immediate relatives, not including parents in the US, shall I put my fiancee as my relative? (Yes, I know it says on the right-hand side that "fiance", but some people in this forum said it should be "no", which is a bit confusing what is the right answer for this).
For the question about the person/entity paying for your trip, shall I put SELF or US Petitioner on a K1 visa? (Since the petitioner files the I134 form and sponsors beneficiary, should it be the US petitioner then?)
For the question have you attended any educational institutions at the secondary level or above? Do you list all your previous education you attended in descending order? Or only the most recent one where you graduated? (Again this question got answered differently by many people)
