You have to meet these conditions for the German passport

The principle should also be retained: Anyone who wants to be naturalized must (be able to) support themselves. How much money you have to earn in the end to meet this requirement often varies. For example, it depends on how many people live in which place and in what living conditions, how many people have to live on the income and whether there are other employed people in the family. The receipt of basic security, citizen’s allowance or similar benefits is therefore considered an obstacle. Unless there are permanent and serious health reasons.
