I am a cadre of a certain military unit. Now my parents emigrated overseas during my service, and I am not married myself. How to deal with it?

Civil servants can emigrate, but they are restricted by certain conditions.

For example, active servicemen, security department staff, secret-related departments, and government officials who need to be audited after leaving their jobs are all restricted. For some special personnel, due to professional reasons, official and personal passports need to be managed by the unit in accordance with regulations, including handling Hong Kong and Macao passes, and also need to be signed and sealed by the unit. As long as you go to the exit-entry administration office to apply for a passport or pass, you have to return to the unit with an application form to sign and stamp it, because these people have already filed it in the exit-entry administration office, and the place where they sign and stamp is on the back of the application form, which is not used by ordinary people and probably not noticed. These measures show that the government is more cautious about the immigration of civil servants.

International civil servants and their families are not subject to this restriction, for example, you work in the United Nations.

Another country that immigrates will also strictly control such people and do some background checks.

You don't have to resign, it depends on your specific situation. Being a civil servant has a certain negative impact on immigrants, but ordinary civil servants have little impact. It's not too late to resign at the last minute, even when you are a policeman and a soldier, you have succeeded.
