We would like to inform you that according to UAE labor law as well as residency law, if you have a visit visa that can be transferred into work but sign a job offer without signing a work contract, you can change or move to a new business area and do not extract any visa for you.
Therefore, if the employer applies for obtaining the visa for you, the duration of the time it takes is sixty days, if this time is exceeded and in order not to fall into residence violations, you can go to the labour office and file a complaint and explain the matter in detail for the purposes of following up by the work office with the employer who applied for the visa
If it turns out that there is no transaction or submission regarding the visa you can move to the new job without any legal responsibility on you and with the knowledge and approval of the employer
