An HIB visa holder has resided continuously in the US since Oct of 2004. He works for joint-venture and his basic salary is paid in home country (Nigeria) He receives a per diem in the US which is also paid by his employer but paid into his US account. This amounted to $90,000 in 2005. Is he considered a tax resident and therefore required to file for 2005. Is he required to report just the US income or even the income in his home country?
Thank you
