I flew with a guy whose papers were lost for a couple of years. Finally he called and they found them. Another friend went to a job fair and told the UPS rep he had been in the pool for pover a year. The guy said "that's too long, why didn't you call us?" at which point my friend pulled out the letter that said "don't call us". These people aren't perfect. They are pretty nice to deal with though so you should be ok giving a call
