K-1 can be filed now, since they have already met. To apply for a visa based on marriage, he would have to first travel there again and get married. Then he could apply for CR-1 (by filing the I-130), and, when he gets the I-797C NOA1 receipt, he could file for K-3. Rather than worrying about a denial, you are better off getting your evidence together yes agreed, but if they intend to marry this year as stated in OP, then K-1 would become invalid, remember processing times are 10- 11 months now. Welcome to CFL. Quick question what are your ages, because in China you have to be a certain age to be able to marry in the first place. I can not think of the age requirements because I am well beyond it and so is Ada the beautiful lady I will be marrying in May if I can get back then. She is 23 and I am 27. A quick question for anyone... if it is certain that we wish to marry, then we cannot get a K1 and marry in the US?
