What D'Bhakta did is nothing out of the ordinary. Btw, I just found out abt it after I came to California. There are quite a few Nepalese who lend their SS cards/numbers to others.....

While I'm perplexed by these people's guts to pull off something as big as these, as long as you  stayed on with "I didn't see anything" policy ( i.e. between the two of "you" and the employer as well ), problems shouldn't arise.

Going back to the original query, You can definitely pen your experience in your resume....but only if your employer is well-informed about it. Else, you, your buddy who allowed you to use his SSN and your employer are set for a few years behind the bar and deportation back to your respective mother lands.
