If you surrender to the embassy, how long can you be repatriated?

Legal analysis: it depends on the decision of the local immigration bureau. Australia will be deported within 28 days. Usually it's the next flight, and they are detained before the next flight, and there are people guarding them.

Legal basis: Article 62 of the Law of People's Republic of China (PRC) on Exit and Entry Administration. Foreigners may be deported under any of the following circumstances:

(1) Being ordered to leave the country within a time limit and failing to leave the country within the time limit;

(2) being refused entry;

(three) illegal residence and illegal employment;

(four) in violation of this law or other laws and administrative regulations, it is necessary to be deported.

Other overseas personnel under any of the circumstances listed in the preceding paragraph may be deported according to law.

Deported persons are not allowed to enter the country for one to five years from the date of expulsion.
