How can I check the immigration status of my friend who absconded from Dubai?

Hi there,

My friend absconded from Dubai in 2008/2009 leaving behind a small amount of credit card debt in Dubai and also left her employment without resigning properly.

If my friend was to fly to Doha, Qatar would this cause a problem? My friend has never been chased by the UAE bank and has never heard from.

Is it possible to check my friend's immigration status?
