H1B Approval notice corrections

Hi,

My H1B petition was approved in 2nd week of September 2013. The approval notice which my attorney has received has incorrect name under First name column. Hence, she has raised a request with USCIS to correct this mistake. It is almost 2 months there is no update from USCIS.

Can any one tell me how much time does it take for processing a correction request on Approval notice with USCIS ?

Also, does the US Shutdown effect could have delayed or slow down the process ?

Is there any tracking system to get the status on correction request ?

Your answers will be greatly appreciated.

Many thanks !

Best Regards,
