Do youbhave an example? I just.find it hard to believe that he would never have a chance...
Examples: People who have made a false claim to US citizenship (inadmissible for life with no waiver), People who have filed frivolous asylum applications (inadmissible for life with no waiver); People deported after certain convictions (depending on conviction, could be lifetime with no waiver possible); persons with a particular pattern/history of unlawful presence/removals combined with unlawful entries may trigger the "Permanent Bar" (bar is "permanent", but waivable 10 years after exit). Please see an experienced immigration attorney who can review his file. You may even want to get a second opinion. But please proceed with caution. The unscrupulous have no problem telling you what you want to hear so that they can get to your money.
I know that it make sense but he had never been in trouble before that, and it was his first attempting to cross... Is it normal he would.get a lifetime bar???
I think that you would understand the law and the consequences of certain actions a bit more if you spoke to an attorney in person.
