20 16 how does Saudi Arabia deal with overstaying?

Generally speaking, the applicant should arrive and leave the destination country within the validity period and stay period of the visa. Otherwise, it is illegal to stay. In serious cases, they may be fined, detained or deported.

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 extend the visa. If the applicant fails to apply for an extension within the stay period, and the validity period and stay period of the visa have expired, and he has not left the country, he must apply for an extension of the visa with the corresponding valid certification materials.
