My girlfriend overstayed when visiting 5 years ago. She was naive and was tricked by a bad person into overstaying without knowing the processes. She believed she was staying as a student as she started attending school, but she didn't receive a student visa after stupidly handing over "application fees". She returned to South Korea on her own, 3 years after her travel visa expired. We want to get married but I can't move to Korea due to a lack of employment options. I've established my career here in the US and can even provide for both of us if necessary. We're getting older now so need to have children soon and we want them to be US citizens. Is there any way to get her into the US? Is there a chance that she isn't even barred? Can we check if she even has a 10 year bar?
