I'm working on OPT right now, and I'm a little confused about which forms I should file. It has been 2 years since I came to the U.S and I won't claim any dependents. Should I file 1040NR or 1040NR-EZ?

Thanks

Form 1040NR-EZ, unless you moved for your OPT and have unreimbursed moving expenses.

Then Form 1040NR with Form 3903.
