Writed some times to support:"Answer: Please wait..."
I also signed up but a bit more recently (approx. 2 weeks ago). For most of that time absolutely nothing has happened with regard to Tether's verification of my ID details. I was getting very concerned so withdrew my Tethers to Poloniex, swapped it for ETH or BTC then transferred that to CoinBase where I sold it for Euros so that I could transfer that to my UK bank. What a fiasco when you think about it, and charges all along the way.
Going back to Tether though; yesterday I noticed that Tether had *finally* updated the ID verification page. They haven't checked/approved it yet (no sections at all and there are several which took many hours to sort out and upload) but at least they've now given me a position in the queue. F.Y.I. it's in excess of number 1500. I also waited to see how many the number dropped by in the last 24 hours and the number is a disappointing 6! So, at that rate, I need to wait another 8+ months before they'll get to even look at my data. Hmm. Not a great system if you ask me but I guess they now have their dollars so probably have no great urgency to swap them back to Tether crypto tokens.
