Is the Client’s presence obligatory when submitting / receiving documents related to migration in the relevant state bodies, if the Client has issued a power of attorney to a lawyer?

Some procedures require the Client to be present when submitting / receiving documents in migration services. For example, when submitting and receiving documents for a temporary residence permit to the migration authority, the presence of the Client to sign the documents is required.

Thus, some procedures require the presence of a person in certain instances, regardless of the power of attorney.
