2) Apply for Dubai PCC-Take all docs-typed forms in Arabic English-Original Passport and Original Emirates ID-to Port Rashid or Muraqqabat Police station- the former is quickest. One at Mulla Plaza consumes more time. The UAE PCC will be ready in 2 working days.
3) Apply for your Indian PCC (u Cannot get it done at the consulate-they outsourced it to BLS Intl; etc- so Al Khaleej Building next to Jumbo and near Deira City Centre {IInd FLOOR, 202, Dubai National Insurance Building, NEAR FLORA CREEK HOTEL ,Plot No. 315 (129-134)Port Saeed, DEIRA, DUBAI.} is your best bet!
