I came to US in January 2010 as an F1 MBA student. I graduated in May 2012 and my OPT started in July 2012. I got offered a 6+ month contract position job and HR requested me to complete a W9 form. (I already have a social security number I got when I was working on campus.) Is that the right form to complete or should I complete W8? Am I considered as other US person (US resident Alien) or not? What is the right hiring process?
