hadrons123 posted a topic in DoctorsI am on a B1 visa with i94 ending on march first week. I have got a DS2019 form from my university to join research position on january 1 ,2015. I wanted to know if it is advisable to do a status change with i539 form by staying in US. Since i recieved the DS2019 form on a short notice, I have not made travel plans to my home country. I understand that I would not be able to take up the research position until I get a approval of status change from USCIS. I was told it usually takes 2-4 months.
