Urgent Attn Reqd: Work Location during H1b Extn

[h1bworker1979]

My H1B visa is going to expire shortly and my employer has filed for extension on 27-Aug-2013. Currently, I hold LCA for two locations ( say Location A and Location B) and the work location address provided for H1B Extension is Location A. Due to last moment changes, it has been decided that Location B should be my base location.

 

1. Can I change the Work Location to Location B in the H1B extension, while the visa extension is pending? Will it incur additional costs? Both Location A and B are for same company and same client.

 

2. Can I travel between Location A and B, while the extension is in progress? Will it call for an RFE, if I travel between these two locations?

 

Immediate attention is highly appreciated.

 

Thank You.
