OPT->H1->EAD(from pending 485), tax treaty?
Dear tax expert,
I was on OPT/F1 till 06/05, on H1 from 06/05 to 08/05, then I started using my EAD obtained from my pending 485 from 09/05. I understand I can file as resident and use 1040 base on the substantial presence test as it is over 183 days since I used H1. But there is no case example for EAD from pending 485, can you confirm me this?
My questions are:
1. Since I was on OPT till 06/05 with no SS and medicare paid (but they did tax me on federal for all the income during that period, strange? But true), can I still use the tax treaty on top of the standard deduction and personal exemption? If not, why? Any references?
2. My kid doesn't have a SSN but has 485 pending, can I get child tax credit for him?
Thanks a lot!
