H1B Urgent - Incorrect name in I 797 ( First to Last and Last to First Name)

[chennaiguy2018]

Hi,

I have received my I 129 and I 797 approval copy from my employer for H1B visa stamping. I noticed the below error:

Name in Passport:

First Name (Given Name): ABC

Last Name (SurName): XYZ (actually my father name is here)

Name printed in I 129 & I 797 copy:

First Name (Given Name): XYZ (actually my father name is here)

Last Name (SurName): ABC



I am worried and i have below question:

1. Do i need to change the name before stamping?? ( Is it okay to change it later on) ( because except this I 129 and I 797) i have correct names.

2. There is no letter missed .Instead it was misplaced

3. If suppose, i need to change it before stamping , please let me know the procedure, time for processing and fees?
