You must pay a fee if you overstay your visa validity. You must travel to the Tanzania Immigration Head Office in Dar es Salaam if you find you have overstayed your visa. After paying a $600 fine, you'll be given a pass. There is no getting around the penalty, and everyone who has overstayed their visa must pay.
Example: Your visa is valid through January 12, but you remain until January 14. You must then pay the fine.
To avoid these repercussions, you must follow visa restrictions and depart Tanzania before your visa expires. If you have already overstayed your visa, it is critical that you handle the matter as soon as possible. To discuss your issue and explore your alternatives for addressing your immigration status, contact the Tanzanian Immigration Services or the nearest Tanzanian embassy or consulate. Resolving the overstay as soon as possible might assist to reduce potential issues and fines.
