Hi mam ho are you i want to ask about my visa i...

Although your query is not clear, here is the following information:
As long as you have a valid residency in the UAE, you can leave the country and return again during the period of validity of the residency.
But we advise not to leave the country without obtaining written permission from the employer to approve your departure for work and travel to Pakistan.
As leaving work and travel without obtaining the consent of the employer is a matter that gives the employer the right to terminate the employment contract.
