It should be noted that in the UAE, possession and trading in drugs is a very serious crime and UAE has a zero-tolerance policy for anyone involved in this type of crime. Your case is beyond the authority of the courts in Dubai as the court did pronounce a judgment against you. Therefore, you may consider making a request to the government of Dubai and the federal government of the United Arab Emirates to grant you permission to enter the country. You may consult a legal practitioner in the UAE and take further guidance in this matter.
