Can I apply for visiting relatives in Finland many times in one year?

I understand your feelings, but unfortunately, this problem cannot be solved. If you apply for an extension when your visa is about to expire, the Finnish Immigration Bureau will reject your application within a few days and leave a bad record, which may affect your application for a visa in Finland in the future. If you want to apply for long-term residence in Finland to reunite with your family, it is almost impossible for Finland to reunite with your parents because Finland's attitude towards immigrants is not very open. I have been in Finland for more than ten years, and I only saw a family in China send their parents there. That's because their parents are younger, so they hired their parents to work in the restaurant through their own restaurant, so they moved down slowly.
