I have met a Russian woman with a USA business visa good until 12/07. If she comes to USA for marriage to me in 08/07, can she stay in USA after we are married or can there be problems where she would have to return to Russia until a K-3 visa can be issued to her? I am hoping i can obtain all the necessary papers (AOS, SS#, green card, etc.) while she is here so she will not have to return. Please help with answers or links!!!!!
If I take what you wrote at face value, the woman is not currently in the USA. The plan is to come to the USA in August and marry you. She can do that but she must return to Russia instead of staying here to adjust status. Coming to the USA with the intention of marriage and status adjustment is only allowed with a K1 visa. To do so on another visa type (and attempt to adjust status) is visa fraud.
If she is coming here in August, you can marry but sometime before her visa expires or for a K3 or CR1 interview she must return to Russia. The visa interview will be in Russia.
If I've misunderstood, and she was already here before you decided to marry, is still here and will remain, then yes, she can stay and adjust status.
