If you have been outside the UAE for five months, in this case, you can return to the UAE as long as you have not resided outside the country for six consecutive months and we advise that you adhere to the duration of the leave so that the Employer does not dismiss you from work if you are absent from work for seven consecutive days or twenty separate days by the text of Article 120 of the UAE Labor Law and we also advise you to contact the General Directorate of Residency before returning to the UAE to make sure that your residency is still valid and has not been canceled.
