Question: I have received a mail copy of visa for dubai.?
Will it be enough to show the email copy at indian airport from where i will depart, or I’ll need a fax copy of my visa.
however, I will be receiveng the original visa after arrival at dubai airport…
Get the copy of your Visa no matter email or fax and present it to the Airport from the place you gonna depart. there would be absolutely no problems 
YES, the printed visa copy will be enough for the arrival. When you reach Immigration section at the Airport present your visa copy and your original visa will be there for the verification.
Give your answer to this question please!
