My name is Ambreen and I am Pakistani national. I was engaged with U.S national person (Umar) in 2011. I went to U.S on K1 visa in 2012. All of sudden my father fell ill and I had to come back to Pakistan in emergency without getting married with my fiancé but I got pregnancy. My son born in Pakistan and has got U.S nationality through C.R.B.A. I and Umar (my fiancé) want to be in relation again. Do we need to initiate whole process of K1 visa category from very start or we can continue previous one? Please let me know one thing more that do Umar need to visit Pakistan again which is one of the requirements of K1 visa or not?
