PERM Applied Job location change

[Prasad99]

Hi,

I am in my sixth year if H1b and due to closing down of my office location I have to move from MA state to NY.

My employer applied for my PERM in FEB, 12 and still under review. No change in my employer and no change in job responsibilities, just the change in location from where I work.

Do they have to apply for new PERM again or just have file amendment to existing PERM application ?

My h1b visa expires on Jun 30th and it can be extended until MAR,2013 (max)

I appreciate if you have any advise for me....
