What options do I have if my rental lease is in my partner's name and the landlord doesn't want a foreigner living there?

The individual is facing a situation where they are living in a rental property that is under their partner's name. The landlord is unwilling to officially acknowledge their residence because they did not intend for a foreigner to inhabit the property. A suggested course of action is to visit the immigration office with a copy of the lease to explore possible solutions.
