To make the long story short, could you ask your buddy on what ground he was considered to be inadmissible?

From tids-bits of your story, I am assuming ‘212(a)(6)(C)(i)’ = Misrepresentation . As you mentioned, ….indian officer dude and he said “ Jo bhi hai sach bataao….”

Now earlier you mentioned “ Officers saw his picture while at work in his cell fone and stuffs started from there….”….I personally don’t buy this story, but just for a moment let’s assume this is true…

Federal regulation does put the burden on the alien to satisfy the examining immigration officer of the claim of lawful admission……however if the immigration officer thinks the person is inadmissible then the burden is on them to show/prove it….there is whole bunch of process involved in it, and just phone pictures would not prove anything……what made the immigration officer think..there was misrepresentation of info?…..Only, if they have a cause to believe that there is in-fact a misrepresentation of info, they would probably check other docs, may be phone, laptop……they would probably have a statement, some sort of form with their side of facts and evidence…and your buddy statement…they should have probably given him some sort of number/code for which the grounds of inadmissibility has been proven……

I don’t know much about Laws, but with tids-bits information, no one can give a proper suggestion.....with little details, you are leaving things on our imagination to fill the gap of details, and trust me in this way your buddy will not get any reliable advice through sajha…

If your buddy does not want to share other info. getting a lawyer is the only option….cause rules/ regulations gets very tricky….there might be a waiver form that can be of help….
