dMy fiance and I are getting married in England on Nov 17th 2012. She is a full british citizen and I am a full US citizen. We are moving from the UK to the US in January for me to take a new job. If we apply in November for her I-130 and her K-3, would she still be allowed to travel (Standard ESTA) to and from the US? We could show return flights, UK bank accounts, home ownership in the UK, etc.. Also, how long would we expect this to take and is it better to apply through Chicago Lock Box or through the US embassy in London (Which has it's own immigration unit)? I have my parents address as well as a home that I own in Chicago, so could apply from there as well. Just want to know what's fastest and keep her out of trouble. Thanks!
