What if the visa for going abroad expires?

If your visa expires abroad, you must go to the local immigration office for extension in time. If the applicant really needs to extend the stay period due to special reasons, he should apply to the immigration authorities of the destination country for an extension in advance during the stay period. If there are sufficient reasons, it is possible to grant an extension. If the applicant fails to apply for an extension within the period of stay, and the validity of the visa and the period of stay have expired, and he has not left the country, he must apply for an extension with the corresponding valid certification materials.

If the applicant does not apply for an extension during the stay period, and the validity period and stay period of the visa have expired, and I have not left the country, then I must apply for an extension to the country I went to with the corresponding valid certification materials. So as not to be punished as an illegal resident.
