It will take several years to re-enter Dubai after being sent back.

After being sent back to China by Dubai, it will take some time to re-enter the country. The specific waiting time depends on your specific situation, including the reasons for being repatriated before, the time of repatriation and personal background.

According to the provisions of the Exit and Entry Administration Law, foreigners who are deported are generally not allowed to enter the country within 1 year to 5 years from the date of deportation. If they enter the country within the prescribed time limit, the customs will also repatriate the parties.

Therefore, if you want to re-enter Dubai, you need to carefully understand local laws and regulations, contact relevant departments, and get accurate entry time and requirements. I suggest you consult your local immigration office or embassy for more detailed information and guidance.
