Hello and welcome to the Wefugees Community!
It would be helpful to have the quotation of the whole sentence you are referring to. I assume it is mentioning the re-entry ban which will be issued after a deportation. You may also check Handbook Germany’s information on this (under “what are the consequences…”).
In any case, please also don’t hesitate to get back to us with any further questions.
All the best,
Meike
