For many countries entry into Doha requires a visa. There are two types, a transit visa (for visits between 5 and 96 hours) or a single-entry visa valid for one month.
The transit visa is free to travellers that are transiting through Qatar via Qatar airlines. This has been implemented in a bid to start promoting Qatar as a reasonable transit hub, and to boost tourism of the region.
You need to apply for the visa at least 7 days before arriving in Qatar. We had some difficulty with the beloved’s application, as the Qatar authorities require a high resolution scan of the passport (not a photo) and the NZ passport has a number of security features to ensure you are unable to get a clean scan. However, that being said, they accepted my documentation, and I was issued a transit visa.
The beloved received his visa on arrival directly at immigration. A one month visa was provided upon payment of 100 QAR, and the best way to pay for this is via credit card (they do have cash facilities however there is a fee to use cash and this is done prior to reaching the immigration counter).
