How many of you got certificate of residency after notification with TM30? For opening bank account, getting driving licence,..

.​And what about the yellow book possible with DTV?

I still think about getting ED type visa for getting permit to stay as a student of a language course. As DTV seems like "non-Immigration" visa for short stay (same like these days 60 days visa for tourists) and ED type visa as immigration visa category. And only with the immigration category visa is possible to get the certificate of residency I guess.

In fact DTV is for more than 90 days so should be in category of immigration visa. Is that really notified as the same category as any other visa valid longer that 90 days?
