Hi, I have been filing tax returns with 1040NR-EZ form since 2013. I entered the US with F1 in Aug 2013 and I stayed more than 330 days in the US each year except 2013. I recently talked with someone who suggested that I should count my visit to the US in 2012 with ESTA. If I count that visit (~7 days), 2017 would be 6th year so that I considered as resident alien for tax purpose. Would you let me know if I can file tax return as resident alien?
