It might be due to being soft power. I wonder what would happen once you finish the classes? I mean, I know that in theory the visa is good for 5 years, but, at the same time, it's granted on something that might not last for 5 years 👀🤷🏻
in many countries we have two names. The second would be like the equivalent of middle name in the US, but it's literally called second first name on the local language. I also have one. Never use it except for official forms (as it's printed in my passport).
ah, well, yes, if the landlords gives you their ID and password. But I think the problem here is that landlord doesn't want to do anything related with Immigration.
