Probably they don't turn away groups where one is a Mexican. I get to skip even the Mexican line, so I honestly don't know. I do know that some of the bosses there don't think FM2 and FM3 holders should use the Mexican line.
Although the lines may be long, the wait is well worth it. If you know what is waiting for you on the other side, you will brave the line any way and walk out smiling.
I just talked with someone who is in the Mexico City airport right this minute. The line for INM there was over 2 hours! It's bad everywhere.
is there an email that you know of where we can complain?. . .I looked on the goverment website posted and didn't see an email address. . .that would sure be handy
