Could somebody help me out with my query..

I'm visiting Dubai for 8 days and already have my TRANSIT visa for those days through the hotel.

Then I leave for 3 days to Jordan, and then just come back to the country to catch a plane from Dubai to Atlanta.

The thing is I fly in to UAE via Sharjah Airport, and then just need to connect to Dubai International Airport to grab my onward flight.

My question is about the 96HOUR Visa. I checked in many websites and it says you have to be minimun 5 hours in the country to be eligible.
My flight in to Sharjah arrives at 7:20PM, and my flight from Dubai leaves at 11:35PM. There is a gap of 4hours and 15 minutes..

I just need to transfer from one airport to the other.. Is this possible? Would I be denied visa for not filling the 5 hours?

Just so you know, Im a Mexican citizen with a Mexican passport.

Please someone help me out, I'm going crazy not knowing what to do!!
