Is it legal for the US Mission to resign urgently?

Illegal. Your hasty resignation has caused economic losses to the employer (employer's certificate), and the employer shall deduct no more than 20% at most.

According to the labor law, the company leaders should be notified in writing one month in advance, and the resignation application should not be written in the written notice (because if it is an application, the company can approve it or not, but if it is a resignation report, there is no problem for the company to approve it for you). ? But some companies will think that your heart is not at work, and there are many people who can take your place. Why should I pay you to take up company resources? In this case, the company usually allows employees to leave their jobs within one month. If the company is serious, you can only stay for 1 month. Most companies require a written application 1 month in advance, which usually takes 1-2 weeks to complete. But if the company is a little dead, it must be 1 month in advance, and you won't let people go until the time is up.
