I sent my supporting document by USPS express mail to TSC. the confirm signature was sent to me a few days later after delivery. however, I found the mail stop code is different from what i wrote. that is, the singed address is 75185-1488 rather than 75185-1391. and I did not see any change of my LUD! is there any problem? is there any one have similar situation? how can I confirm whether they have received my documents?
