I was working with a company and got an offer with...

We would like to inform you that if you are an expat in UAE and you want to cancel the visa to change the employer, then you have to note that only the sponsor or who represents him can cancel the visa and to proceed with the cancellation of residence visas guaranteed by the sponsor, and the sponsored person can not proceed without permission and signature of the sponsor.
In case the company decides to cancel the work visa for the employee, it should first refer to the Ministry of Human Resources and Emiratisation requesting the cancellation of the employment contract and the work card of the employee. This application must be signed by both the employer and the employee, accompanied by a letter signed by the employee confirming that he has received all his salaries, benefits and end of service from the company.
After the cancellation is completed by the Ministry of Human Resources and Emiratisation, only the sponsor can apply for the cancellation of the residence visa before the General Directorate of Residency and Foreigners Affairs in the Emirate concerned.
For family (or personal) residence visas, such as the spouse of his wife, children and dependents, the sponsored person must first cancel his or her sponsored visa before he / she cancels his or her residence visa.
Cancellations can be made through the General Directorate of Residency and Foreigners' Affairs, which first issued a residence visa in the Emirate concerned.
The following documents must be attached and presented when applying for the cancellation of a residence visa at the General Directorate of Residency and Foreigners Affairs:
• Cancellation application form signed by the sponsor
• In case the sponsor is a company or establishment, the application shall include the signature and seal of the company, accompanied by a letter of clearance and the completion of the procedures by the Ministry of Human Resources and Emiratisation.
• Original passport of the sponsored person
• Original ID card of the sponsored person
• If the sponsored person is outside the country, the original passport must be brought.
• Normally, the cancellation request can be completed in one day or less, depending on the applicant completing all documents and requirements.
• After cancellation, the sponsored person is given a 30-day grace period to either leave the country or obtain another residence visa, and no fines apply during the grace period.

Dear thank you for clarification, the matter is related to security approval, and this is a matter for the Ministry of Interior. No one is allowed to ask about its reasons, regardless of nationality. For example, if you apply for a visa from Dubai, you can apply and request it from the emirate of Abu Dhabi, and vice versa, thank you

We are always happy to contact you in the legal department
