I checked the site of UAE government visa:
In this, the requirements of visa on arrival for Indians is mentioned as:
Indian citizens holding a normal passport and either - a visit visa issued by the USA or - a green card issued by the USA or - a residence visa issued by the UK or - a residence visa issued by the EU can obtain a visa on arrival for a maximum stay of 14 days provided that the visas or the green card is valid for at least six months from the date of arrival into the UAE.
It says, having a visit visa issued by USA. I have H1B visa and my wife is on H4 visa. Can we get on arrival visa in Dubai on these visas or not?
