I was an exchange student with F1 visa in 2012. Then I went back to my home country (whole 2013 was at my home country). Then I went to US to get graduate degree in August 2014. I was in F1 from 2014 to July 2018. I got H1B in August 2018. Am I a resident alien or non-resident alien in 2018? Could I use turbotax? Thanks a lot for your help.
You are allowed to exempt days of presence on an F1 visa for 5 years or part years. Your 5 years were 2012, 2014, 2015, 2016 and 2017. You became a resident on January 1, 2018.
You will need to file a US resident return and claim your worldwide income for calendar year 2018.
You can use TurboTax.
