How long can the blacklist of the Philippines be lifted?

Can't lift it. The blacklist in the Philippines is permanent, that is to say, once personal information appears on the blacklist of the Philippine Immigration Bureau, the blacklist is permanent and will not disappear automatically. If you want to enter the Philippines, you will be refused a visa. If you want to enter the Philippines through landing visa, the best result is to be repatriated directly, and you may be repatriated because of the blacklist.
