just wanted to help people who think you have no options when traveling to the usa on a visa and have been unfairly question and detained. there is a program in place called "travel redress inquiry program". you apply to homeland security to review your visa situation. homeland will review your entry and exits and assign you a number to be used with the immigration office upon entry and relieves that person of any decision regarding you standing with immigration. you pass through because someone in a higher position has green lighted your visa. it came up 2 years ago with my colombian girlfriend. she spent 6 months and 1 day in the usa in 2014, not continuous, because a scheduling problem with the airlines. they held her in immigration and questioned her making her miss her connection. i hired an attorney for 300.00 and submitted a request for review. the attorney stated you can not lose your visa on multible visits that add up to more than 6 months. you can only lose it on a continuous stay the first day past 6 months. it becomes invalid at that point. the higher ups agreed. the attorney said immigration makes its own rules at the gate. it is unwise to pass through immigration on the weekends because you have the B team with power to turn you around. with her number in hand she has had no further problems. hope this helps. maybe the argentine artist got the B team.
