I have been in US for 2 years as a j1 "research scholar" visa holder. I came back to China last Oct. Before I came back, I only paid the security and medical tax.
I am planning to go to US as a J1 short-term visa holder around this Jun. and will stay in US for 6 months. My question is what taxes I should pay for revisiting (what tax benefits will I have?).
Thanks!
