Employer address change : Moving work location / building

[inspire11]

Background

• I am working as a full time employee with a company of around 800 - 1000 employees.

Fact

• My LCA, I-797 & petition forms have the current building / location address as my work location

Issue

• My employer is changing address by moving to a nearby building / shifting location.
• Within 3 miles radius.

Worry

• I need to go to India for H1B stamping (first time) in two months.

Questions

• Does my lawyer need to file any LCA / H1B amendment for new address ?
• Do I have to ask my lawyer to inform USCIS of the address change ?
• DS 160 Form : What should I put as my work address here now as the address will be different than the one on my I797 form and LCA
• Can any issues come up during H1B stamping ?

Please provide your valuable repsonses.

Thank you.
