Good evening…
I’m flying from India to Tanzania with a layover in Dubai on Emirates, and I’ve got a couple of questions. 
Can I get a transit visa through Emirates? Also, will I get stamped in Dubai during my layover, or is it just a quick stop with no immigration stuff? 
I’d really appreciate any info or experiences you’ve had with this
Best wishes…
