Can i travel within 10 days of my VISA expiry

My H1B is getting expired on feb 28th of this year. My employer is in the process of initiating the Cap Exempt for my H1B. Can i travel before my VISA gets expired i.e., before Feb 28th and then extend it from US.

Are they ready w/ all the paperwork including LCA? You can enter 10 days prior to H-1 visa expiration date, but your employer should be able to file the extension petition before the petition and I-94 expires.

Ask your employer where specifically they are in the process of petition filing.
