Hi,
I entered US since 2014 with F1, then worked using F1-OPT until 2019 February.
Then I left for Canada due to OPT expiration and get back on 2019 December with H1B.
So I've stayed in US for about ~60 days in 2019, it doesn't count to 180 days criteria.
For the Substantial Presence Test, should I count my days back in 2018 and 2017 since I was on F-1?
In my case can I just file 1040-NR instead of Dual Status?
