Hello, can I ask a question about my colleague was...

We would like to inform you that according to the Federal Residence Law regarding organizing the residence of expatriates in the country, if you leave the country and not return for more than six months, residence will be canceled, even if it is valid
In addition, the sponsor can file an escape report against you, which entails the ban
But there are exceptional cases if the residence is excluded outside the country, then the sponsor can request an extension at the immigration and residence for foreigners, so you shall coordinate with the sponsor in this regard.
