Only when I left the country did I find my passport canceled! Check whether the passport is valid in this way.

Attention should be paid before traveling: check the validity of the certificate!

If you want to go abroad, you should check the latest passport status in advance. Once it expires, you should apply again. Don't find your passport canceled at the airport.

You can check whether the passport is valid through the following methods

WeChat searches for "Immigration Bureau" and enters the immigration administration mini-program. The page will have a one-click entry program for business handling, certificate inquiry and entry and exit information. It is enough to enter the options that need to be inquired.

If the certificate is gray, the certificate has expired. If the passport is lotus color, it is a valid usable document, and if the passport is blue, it is a valid usable document.

In the upper corner of Alipay's home page, search for entry and exit business queries in the search bar, which can be queried according to the procedures.

If the detailed entry and exit records can be displayed, it proves that the documents held are valid and usable; if the entry and exit records cannot be displayed, it proves that the documents held are invalid and invalid.

ITU consults the issuing authority for verification.

This query result is the most accurate, but the process will be more troublesome. You are required to inquire about the relevant information of the issuing authority, and transfer and verify the information during the ITU consultation.
