I would like to ask about a letter which I received from BAMF. I have finished 3 years with having the blue passport (Reiseausweis) and I applied for prolongation. Few days ago I received a letter stating " "Belehrung über Mitwirkungspflichten im Widerrufs- bzw. Rücknahmeverfahren" from BAMF Eisenhüttenstadt in Frankfurt Oder. They asked to answer some questions to send back but the problem is that there are no questions in the letter. Also, it was written that the letter with the answers must be sent back within a fixed date (otherwise I would have to pay the penalty for not cooperating) but there was no date written on the letter. I would like to ask what I can do in this situation because it is important to send this letter back with the answers.
I hope you can help me.
