What happens if someone fails to return to China after their visa expires abroad?

First, if the stay time exceeds the stay period approved by the embassy, there will be detention problems. If the circumstances are serious, criminal detention shall be imposed, and criminal responsibility shall be investigated; if the circumstances are minor, criminal detention shall be imposed. If the customs staff is better, you may be released after only one and a half days' delay, but I suggest you return to China normally.

Secondly, the situation of forced repatriation does not apply to everyone. If you are forced to return to China, what you will see in the short term is that you will not go to these countries in the future, but the stain on your personal file cannot be washed away;

Third, in this case, can you still get visas from developed countries in Europe and America?

The advice of the donkey friend, I hope it will help you!
