Pls help Mr. Subramanya - Name change on I-797

[h1bquery]

Hi,

Can someone please tell me how to get the name amended/corrected on an approved I-797?

Also, how long does the entire process take? Would really appreciate if someone gave me an idea on how to do it.

I need to change the name on the I-797 from maiden name to married name as there is a mismatch between my approved petition and active passport.

Will a letter from the employer explaining the situation help?


Thank you
