Having Green Card interview next week. We are married for 8 years but live apart for 5 years for career reasons. Our son is US citizen, he is 7 now. I moved to USA to different state from where my husband lives as I have job perspective here and many lifetime friends who helped me settle with kido. We are basically petitioning for me and if that works - either I move to my husband's state or he comes here. What is the best way to convey this message at the interview as I am sure we will be asked.
