I was on OPT before my H1B is approved on in 2014 but I left US on Aug 2014 and returned with H1B visa on Dec 29, 2014. My company start paying me on Jan 5, 2015. I was working as H1b for the whole 2015 only traveled back for two weeks in summer to get married. Do I have the first year choice? Or I just file as residence alien? My husband is entering the six year of F1 in 2015. Should we file jointly or separately? Sorry about those many questions.
