is it possible to come back to qatar after 6 months?

By DINEESH KUMAR •
i have a residence permit upto 6/06/2011,but now iam in my home town due to health problems for more than 7 months ...
is it possible to comeback now with the same sponsor.
i heard that after 6 months visa will automatically cancel.
is there any option to change automatic cancellation if iam coming with the same sponsor and visa ......please help me?
Go to this link www.moi.gov.qa/site/english/ and type your visa no than you came to know your status
I think its possible but as far as i know, someone here has to pay 500 QR before your 6 months expire. Not sure if the rule is valid even after the 6 months have expired. Let others reply.
