пребывание в стране
Если погуглить, то многие сайты говорят о том, что в то время, как в Германии нет "retirement visa", можно обратиться за временным ВНЖ. Одобрение - не гарантировано.
"Getting a retirement German visa is not guaranteed and is subject to the discretion of immigration authorities, although it may be easier in certain cases, for example, if you are joining a family member living in Germany. Read more on German residence permits.
For all third-country nationals, the initial visa issued is a temporary residence permit (Aufenthaltserlaubnis), which is typically valid for one year, but can be longer depending on your circumstances. Unless your circumstances have changed, the renewal process is generally a formality. After a five-year period, both third-country and
EU nationals can receive a settlement permit (Niederlassungserlaubnis)."
