This is general information : A great Forum www.immihelp.com which provides help and assistance for Visas to USA seems to have been hacked today.
It is unfortunate that spammers and hackers attack any website without understanding the implication it might have on people who are dependent on it. In the mean time allied visa services will try to provide as much assistance as it can. Of course no one can compete with immihelp.com, so we hope they come back up soon !!
