F1 to H1B to F1 - Resident or Non-Resident Alien?

[ivy1990]

Hi all,

Searched a lot and read the Alien Residency Examples on the IRS website, but still confused. Really appreciate any help on this topic. Situation below:

• Moved to US for the first time in 2011 in F1 - did a Master's and worked under OPT till Oct 2014
• Transitioned to H1B and worked till July 2018 on H1B
• Changed back to F1 for a 2nd Master's and currently studying full time under F1 (asking in March 2020, for anyone look at this much later)

Would I be considered a Resident or Non-Resident Alien?

Basically, is it the case that after the first 5 years under F1, we are always resident aliens or are there circumstances when you can become a non-resident alien again?

Thank you very much,
Ram
