Is it necessary to close the IDP certificate when traveling abroad?

One of the grounds for revoking the validity of a certificate of registration of an IDP and entering information about it in the Unified Information Database is departure to a permanent place of residence abroad.

If you do not plan to leave your permanent place of residence, but temporarily, then if you do not notify about your return to the abandoned place of permanent residence, the decision to cancel the validity of the certificate is made on the basis of information about the long-term absence (more than 60 days) of the person at the place of residence , which gives reasonable grounds to believe that an internally displaced person has returned to the abandoned place of permanent residence.

That is, you do not have to remove yourself, if you are not known about within 60 days, then you will be automatically removed from the IDP status.
