You are not the first and you are not the last. First they need a green card, some more patient make kids and wait for passport also. Overall she god what she wanted, so you will be a history soon.
I always advice to guys do not bring any foreign woman here, why you need this headache?! America is not that place where people from outside can be reliable, their head start to spin from all the opportunities they can get, especially women. Pack your bags and go yourself to her place for some time, but why you go through all this headache with documents for her?! She can come here on a visa as well. I dont know not a single guy who did not divorce her first foreign cutie. They got the papers and next day they were gone, especially those J1 students smart ladies.
