Thank you in advance for any help you can provide.
I'm a visiting researcher in a US public university.
I have a J1 VISA which will expires at the end of May 2011.
Now i need to leave the US for a period of 5-6 months for family issues.
I wanted to know if this will affect my VISa status. In other words, can i come back in May or June without any problem at the airport custom?
