Hey John, it's Tillie here. I'm sorry to hear about how your application turned out, but it's good to know that you are moving on.
If Tony & I were in your situation, I'd choose CR-1, at this stage. Yes, it will take longer than K-1 but we've already proven that time and distance won't keep us from loving and supporting each other. We've survived and nurtured each other while in a long distance relationship for almost 3 years, what other hurdles can we not overcome together? At this point, I would feel more secured knowing that we are married while we go through the process of finally being physically together. Plus, going through another interview in a different circumstance (from K-1 to CR-1) would be a huge relief. The stress and pressure will definitely be lesser.
I wish you all the best in what ever you and Rose decide on. Be persistent in keeping her involved in the decision process. Filipino women are used to being submissive to their man because that's our culture - the man of the house has the final say, most of the time. Do not accept the "what ever you think is best" answer. I'm pretty sure she thinks and feels differently.
Good luck to you both. Hang in there.
