Ultimately it is your decision. But that sounds like a reasonable course of action. Withdrawing the I-129F explaining that it was hasty, and you and fiancee wanted to develop relationship longer probably would look good and logical to USCIS. Would give you more time to truly decide about relationship, and looks the same to the interviewing officer. Gives more time to develop evidence of a bonafide relationship. I would study the Post Interview forum paying attention to the denials. http://candleforlove...erview-results/ Here is one relevant, Started as K-1, then switched to CR-1... http://candleforlove...nce-what-to-do/ ( This one was odd, petitioner did not elaborate about denial reason, however he did hint at over spending, sounded like a well off guy going for a trophy wife, something to avoid. ) Yes I'll let it settle for a couple of days but I'm thinking this is the best plan of action. We can test out the relationship with our travels, make sure to take lots of photos, save our travel tickets, hotel receipts, etc, and make sure to document everything up the wazoo. Meanwhile I can study up on the denial reasons and do everything to avoid them. From what I understand age difference is not enough to deny a visa as long as everything else is in place. So I'll manage all the details, make sure she's prepared and involved, and front load the petition with as much information as possible, including the EOR letter. I spoke with her today and she doesn't have a problem with waiting and marrying in China, actually she said as long as I come up with an "awesome" proposal. I really appreciate the help!
