Met in 2009. Filed for K-1 in 2010 but cancelled it before the interview and filed for CR-1 in 2015 instead. POE in 2017, filed for and received Naturalization in 2020.
isn't the number supposed to be on the cancelled check?? We didn't send a cheque (we used money order), so we had to actually wait to get the hard copy of NoA1 to find out WAC#... but I thought it was on the check!!
