My step father was charge with possession of meth, and plea bargain down to a misdemeanor of probation and fines. This charge was from 2003. My father was able to renew his green card about 6 months ago with out any issues, but then after he traveled from mexico to Huston tx, and was detained at the airport of Huston tx and told that he was being detain for a criminal record of meth charge on file. Is this even possible? Do airport have access to criminal files? Do airport security have access to immigration files? And if that was the case why would they even consider a case that has been 11 years old, since immigration knew about his plea bargain when he went to renew his case. can you please help me with these question? I am so confuse?
