I was really nervous a few years back during the Olympics visa crunch. I got my 10-day GTFO visa and I thought that was it. But I went home and did things (semi) properly and got a Z from the embassy in DC. But then I thought, just wait until you try to get through Immigration! No prob. Ah, but just wait until you try to get your RP! Again, no problem.
No one said boo until two or three visas later, when I went to Pudong to get an L extended. Sniveling b!tch flipped around my passport looking for evidence of atrocities. A-ha! She about had a fit over this two-year-old exit visa. I tried to explain that I had been tricked by some shady visa company that I’d been referred to by my employer. Ah, but how to account for hundreds of years of humiliation? She went to get a supervisor. I smiled. Real good and honest. He said never mind.
Anyway, give a rule-crazy pig farmer a badge, and she can make things difficult. Even if you’d thought you were in the clear.
