The Police and Border Guard have released a press release according to which applications for residence permits for the next year are already three quarters of the available quota (1315 in total). When applying after the quota has been reached, the application will be declined. The quota does not affect EU citizens or citizens of Japan and USA. Also the IT sector (i.e start-ups), highly skilled specialists, large investors or people settling with their family members.
Thera are talk about splitting the quota in half so the application process could be spread out for the whole year but the quota number would not change - at least there are no public talks about it. So if you are thinking of applying for a residence permit in Estonia - it is a very last chance to do it already now.
