REMEMBER DO NOT OVERSTAY!! Holding a Chinese Tourist (L) Visa and want to stay longer in China? You can request an extension from the PSB (Public Security Bureau Entry and Exit Administration Office / 公安部出入境管理局) from the city of your stay at least seven days before the expiration of your visa. The applicant can apply for an extension of no longer than 30 days per application . May apply for second or third extension but this depends on the duration of each stay of the original entry visa. Total extensions per entry to China cannot exceed the length of the original permitted stay. However no guarantee that the extension will be granted. The decision will be made by the representative, who will decide according to the situation. Before apply, please contact your nearest PSB for information and requirements. Here are the documents you shall prepare before submission (base on my previous application experience): Basic documents a. Passport - Original passport a
