I change from F1 (OPT) to H1B during 2018 and I'm not sure if I'm qualify for resident in 2018.
I was on F1 from 2015/8 to 2018/6/30 and I stayed in US most of the time from 2015/8/ tile 2018. My H1b started on 2018/7/1. According to SPT, I'm 3 days short from 186 days in 2018. Should I file as non-resident or resident?
Also, in the first half of 2018, I was exempt from Medicare and Social Security tax (OPT status) but after changing to H1B, my company start taking those taxes out of my paycheck. Do I need to specify those changes on my tax return 2018?
