Good day,
I have received a supplement letter from Migri for my RP application. In the request file (PDF), they said they needed some original documents in paper form, whether it should be sent as post or a service point to be visited. Since I don't live in a place that Migri office exists, I have posted my document there. Also, there is a "Reply request" button in EnterFinland too. Should I press the button and acknowledge them that I have sent the post, or should I wait? According to Posti, my document has arrived to the Migri postbox, so how can I get the information that whether they received my letter or not?
