The requirements for legal aid appear capable of being met.
If your own means are not sufficient and the appeal against the entry ban does not appear hopeless from the outset, legal aid under section 8a VwGVG may be available. Depending on the grant it includes the assignment of legal counsel. The application is to be filed with the Federal Administrative Court.
It is important that the appeal deadline is observed. The application for legal aid and the timely appeal should be coordinated so that no deadline is missed.
