1. Even if there is no earthquake, you can apply for an extension of entry for various reasons, but one thing is that you must enter the country within the validity period of your stay qualification (the date of issuance is extended by three months, not a visa), and those who fail to do so will not be allowed to enter the customs.

2. Suspension means that you apply when you have already reported, not when you have not reported. If you don't report, you can't go through the formalities of foreigner registration card, so you can't go through any residence formalities.

3. If you are not in the four counties in the earthquake zone, or if the radiation threat is lifted, the school has not decided to postpone the admission, you can't apply for an extension on the grounds of earthquake or radiation. At least the school won't agree with you. Find another excuse.

4. So always pay attention to the bulletin board of the school you want to go to.
