How long does it take for spouses in Taiwan Province Province to apply for entry permit and immigration documents to be sent to the mainland?

The entry permit is electronic and does not need express delivery. If it is from Taiwan Province Province, you can apply for it yourself. You can go back to Taiwan Province Province or log in to the Immigration Department system through the Internet to download it yourself. If you are from Chinese mainland, you can't handle it yourself. You need a travel agency in Taiwan Province Province, such as an entry permit for Bao Dao, to handle it for you. You can submit materials as invited. Everyone's situation is different. If you need more detailed information, you can visit Taiwan Province through Baidu Bao Dao.
