Form 843 (F1- OPT) refund
I came to US in 2001 and worked on F1-visa (optional practical training) in 2004. But I did not file a tax return. I am filing 1040NR before the deadline in April this year. My question is I want to file form 843 to get my FICA taxes refunded as they were withheld. Is the statute of limitations three years for form 843 also. I am afraid if I will get my FICA back or not since I did not file the tax return originally.
2) should I file 1040 as resident this year and claim deduction for my tution fees paid.
Please let me know
Thank you
