First, our situation was different than yours in that we pursued the I-130 (Petition for Alien Relative) process leading to green card issuance, instead of the K-1 Visa process. Second, we did have a child overseas while our immigration process progressed. Having said this, I will tell you that having a child was the SINGLE MOST VALUABLE life event that facilitated not only initial temporary Visa/Green Card issuance, but also the subsequent Removal of Conditions from the temporary Green Card, and later U.S. Citizenship approval. For example, In preparation for our interview at the U.S. Embassy, we studied the countless possible questions and the appropriate responses based on our relationship. However, when we went for our interview, we were asked only three questions. 'Is that your daughter, [NAME]?" This was in regard to our daughter born in the Dominican Republic. My wife had two children by a previous marriage (my two step-children). The embassy interviewer also asked each step-child their names. This was the total extent of our embassy interview! Later during subsequent immigration steps leading to U.S. Citizenship approval, we had to provide a lot of evidence to prove a bonafide marriage. Receipts and documents related to our children carried the most weight. In fact, we did not submit much of the other evidence as recommended at this site (because we found this site after we submitted our various packages).
