I talked to an immigration lawyer at the start of my process. She told me, basically, that you will be rejected if you use a K-1. She said the best thing to do is have her come here on a tourist visa or visiting scholar visa or whatever, then marry her and apply for an AOS right away. So, I came here, and talked to robertt. I strongly urge anyone in this process to go to him (

He knows his stuff, and he'll help you to have your petition package filled with all the right stuff. I did a K-1 and K-2 for my fiancee and her daughter, and it was done very quickly. In fact, she is going today to pick up the visa, as it has been delivered to her delivery location. Because I'm buying a house and getting it ready, I am not ready for her to be here yet, so we are waiting for the house to be done. I really didn't expect it to be this short, but I believe it was so fast because Robert was so thorough.
Again, I highly recommend him!!!!
