Hi,
One of my good friend wants me to write a letter of sponsorship for him for the Visa process back home.
He is applying for USMLE exam VISA.
Now he sent me a format where I need to put my socoal Security number at the end of the letter.
I am not very much comfortable providing my SSN in a simple letter like Sponsorship.
Now I need your suggestions, If I really need to put my SSN ...
