My work permit. Everyday something new.

3 weeks ago I've submitted an online-application at the USCIS web-site. After I've had to pay the fee (I've already told about the problems I've had with paying it which I have fortunately solved). Simultaneously I had to send some supporting documentation. In paper. By regular post. And here I've made a mistake. I though that I don't have to go to the post office. After all, I'm living in a high-level residence. Normally the hotel of such level is able to assist you with this kind of paper-work. So, I've went to the reception and asked them to send a letter. They've done it. 3 weeks ago. And yesterday the letter came back with indicatied problem that there was... not enough stamps. I'm not even talking about the fact that it took US post service 3 weeks to identify that the mail doesn't have enough stamps and to send it back (everything within 1 state, California and I suppose that if the letter doesn't have enough stamps it doesn't even leave the initial post office). But I was of course extremely angry with the receptionists. Ok, if you don't know the rules, can you just check them before providing your guests with un-checked information which leads to the dramatic consequenses???
Fortunately, as I'm a maniac in terms of timing I've sent the letter early enough to get it now back again early enough to have some more time to re-send the letter (my appointment is scheduled for the 16 of August). So after kicking up a row at the reception I went yesterday to the real post office and sent my documents with the express mail including receipt confirmation option, which costed me 20 dollars but guarantees that the mail will be there 1 day later (today) before 3 p.m. and provides me with a possiblity to track it online.
By the way the front-desk operator at the post office, a middle-aged Asian was exteremely nice and helpful and patient to my not-perfect speaking English. It's just in comparison with russian post-offices which I've not visited since very long time though but which are normally famous for the soviet-style level of customer service.
