I have a valid H1B petition which expires on Sep 2015. my H1B visa has been stamped on Feb 2013. My project currently only has a mexico oppurtunity for which i am currently going through a work permit process ( I am accepting the offer just for monitory gains. My goal is to move to US). I wanted to know just in case after going to Mexico lets say by next year April, if i dont get a US opportunity from my current organization, Can i look for a job in US under different petitioner. Can my H1B be easily transferred. I heard that atleast one time travel to US is necessary from your current petitioner so that the trasfer is possible.
