The Smart:

Twenty years, you have to change the passport. I decided to use a public service website. To access most services, you need to go through a document authentication procedure. And here is the most interesting thing - the passport is invalid, since since the date of birth has been a long time, which I was informed by the system during the check. Called the support, offered to replace the passport to contact the FMS or MFC, and then later... That is, to change the passport through the site, you need to change the passport.

The passport must be valid at the time of registration, not overdue. I had to worry earlier.
And it is better to change the passport sooner, or now for late with the exchange quite often a fine is taken.
