Hello Hassan, thanks for the feedback and welcome to the Dubai visa
1. You could try checking the Dubai Ministry of Labour
website - they have an online checking facility but I don't know if it will work with just your passport. Check with the Dubai immigration helpline
if there is a way to find out your status.
2. If all your papers are in order (degrees attested etc), and you have completed the medical test, then Dubai residence visa
and labour card should be ready in 1-2 weeks I think.
3. I don't know of any particular problems with Dubai Immigration, however you can expect things to slow down over the Eid Al Ahda and UAE National Day holiday break. Dates are from about 26 November to 06 December 2009 with most government departments closed over that period. Sometimes the DNRD works reduced hours.
