According to guides, I should send my papers within 15 working days since I submitted online. The question is - should the letter be already there after these 15 days, or should I just bring it to post within the period? The first variant is not described clearly anywhere, but some things suggest me that it's correct.
But the state post is very slow where I live, and I had to choose it because it's the only organisation in my country sending letters not purcells!
Please help, I'm really worried
