Passport issues in Dubai

Hi! May be you can advise me... I've already in a country with my 60-days limited employment visa and need to finish medicals and other procedure next week. BUT I have no ORIGINAL of 60-days visa (only copy ) and have ENTRY stamp at my passport - Because office at the airport Dubai told me he khows his job better and didn't give the original. And stamped passport.... Is it ok? can I still get the residency visa???
