Dear Parthi dharan,
Welcome backt to the Wefugees Community!
Please have a **** at the responses to your last questions with similar content (i.e. here). One of our experts was giving some important information already.
I am not too familiar with the EU law/freedom of movement. But for an independent residence permit, being able to cover your own costs of living will most probably be a requirement latest after one year/for the extension of the residence permit. Am I right on this @manrhei-mbeon?
All the best,
Meike
