Why do many countries in the world still require citizens of states with a high HDI to get visas?

It seems possible that you may not be asking quite the right question. Many countries require visas from many people. If you squint, you can see some trends like people from really poor countries having a generally harder time travelling elsewhere or authoritarian regimes being more restrictive regarding all movement in and out of the country but in general, requiring some form of prior verification had become the default everywhere.

There are now two big blocks of relatively open countries between which people can come and go both ways increasingly easily (that would be Europe and Latin America) but elsewhere visas are very often required, even for short visits (and in fact, sometimes being tightened or reintroduced under the guise of “electronic authorisation” systems like there is now in the US, Australia, Canada, etc.)

Now, it’s true that a number of countries like Thailand or Turkey do have a pretty liberal visa regime for foreigners from richer countries without too much concern for reciprocity or abuse of the system (and, in spite of what you may believe, overstay from people from rich countries is common). The reason for that is pretty straightforward: Tourism is a major industry and making it easy for people to come for a vacation is a deliberate strategy for these countries. But that’s what it is: A specific reason to drop visa requirements, not the other way around.

It is noteworthy that many of the countries that are “stickiest” about visas for Norwegians are themselves less developed countries. Basically, these may be countries that are suspicious of “anybody.”

The “one” thing that Norway lacks is geopolitical clout, in the manner of the United States, or even China. It is this last factor that may “open doors” to less developed countries for holders of these passports.

This is an interesting question and I’d like to throw in one more answer just because it hasn’t been directly stated yet (though implied in many of the comments).

As others have said, it’s hard if not impossible to completely answer this question with objective sources. Visas are granted/denied for lots of reasons, so trying to pin it down to a single factor (or even a dominant one) is probably not possible. Every country reserves the right to screen those who seek to enter it, and each likely has its own set of reasons for doing so. I’ll give a couple examples from personal experience.

1) USA

The US imports a lot of skilled workers, especially in the tech industry. I happen to work with a lot of people from different countries, and invariably, those hailing from Europe/UK have a fairly easy time getting in. They make great candidates for tech work because they typically come from high-HDI areas where they’ve received a good education and have financial backing, and their skills are in demand. On the flip side, some of my Indian coworkers have had lots of trouble getting visas, because so many Indians want to come to the US but in many cases don’t have the education or finances to match their European counterparts. This all falls in line with your proposition that visas are HDI-related in some way.

2) KSA

Saudi Arabia is known for having some of the strictest visa processing in the world, and is also very high on the HDI scale. But they grant far more visas to laborers from low-HDI countries because they have so much demand for manual labor. Additionally, while I was working there, a government official in the Netherlands decided to make some public slurs about Saudis, and suddenly my Dutch coworkers found it much harder to renew their visas and travel about the country. Some of them even got stuck in Bahrain, being denied reentry until they applied for a new visa. Things like that are clearly not related to a country’s HDI.

Conclusion:

Each country’s motivations are different, and often multi-faceted. It’s probably not possible to tie visa privileges to HDI in any way that broadly applies to the world.

What makes you think people from HDI countries wouldn’t want to work in another country? Not everything is about maximum profit. As a Dutch guy living in Bali (Indonesia) I see plenty of people from well-off countries that still like to live and work in Indonesia instead, many of them on visas that don’t allow this. So coming from a fortunate country doesn’t mean that people don’t have to be checked at all.

A consideration I don’t see mentioned yet is that most repressive governments maintain control over their populations by controlling the flow of information to their citizens – this most visibly achieved by state controlled media and internet access, so that the citizens of these countries only hear what the government wants them to hear. In many of the world’s worst places, an important aspect of this information strategy is convincing the populace that they’re actually better off than the rest of the world. Allowing large numbers of foreign visitors into the country, particularly those from relatively wealthy nations, is problematic because what these foreigners do and say can’t be controlled like the rest of the media, and even their mere existence undermines the illusion that the government uses to keep control over its people. Using visas to limit foreign interactions with their populace is a component of controlling what information their citizens have access to.

I’m struck in particular by the example of North Korea, whose citizens are indoctrinated to believe that their country, and they themselves, are relatively well off, despite rampant starvation and poverty. Seeing (let alone interacting with) millions of fat tourists traveling their country with unimaginable luxuries like multiple sets of clothing and cameras and phones and computers (and so on) would seriously undermine the state propaganda about the relative condition of the native populace, and by extension, the prestige, power and benevolence of the DPRK government. This fiction plays an important role in keeping their population compliant, and keeping them in power, so they’re not about to jeopardize it for a few tourist dollars, especially considering that those tourist dollars wouldn’t add noticeably to the wealth and power of those in charge anyway.

As a rule of thumb, the worse the visa regime, the worse the country’s regime. It’s the tinpot dictatorships of the world (Turkmenistan, North Korea, Saudi Arabia, Angola, etc) that make it the hardest to get visas and watch visitors most closely, not because they’re particularly concerned about Norwegians stealing their jobs, but because they’re afraid that they’re actually {journalists, dangerous infidels, disguised CIA spies, etc} out to {steal their military secrets, report on human rights issues, lead the faithful astray, steal their women, etc}. Or, in the case of the United States, suffering from bed-wetting hysteria about foreign terrorists.

China is somewhere in the middle of the spectrum: not particularly bad as far as visas or regimes are concerned, but still pretty paranoid about foreigners snooping about where they shouldn’t (eg. Tibet without a tour guide) and with a strong preference for more state control rather than less. Inertia is also a factor: no bureaucrat ever got fired for imposing more restrictions, whereas letting a bad apple in may be a career-limiting move.

It’s a good question, and I’ve often wondered this myself. Alamar’s answer is a big part of it. I’m not sure if it adds up to much, but here are a few other things I can think of:

Control

Countries may wish to exercise a certain amount of control regardless. For example, India practices stringent screening of people of Pakistani origin (Even third generation immigrants.) There’s even a special field in the visa application form asking if you have Pakistani roots, and the processing time is much longer for people of Pakistani origin. Many nationalities are eligible to apply for e-visa online, but people of Pakistani origin (regardless of citizenship) are not eligible for e-visa at all. It also appears that a great many of these people are in fact rejected.

To follow up on your example, Norway has roughly 40.000 people of Pakistani origin. (And many more from similar countries.) A great many of them are Norwegian citizens. If India was to remove the visa requirement for all Norwegian citizens, they would lose the ability to additionally screen these Norwegians of Pakistani origin. It would also make it much, much more difficult to reject them. Whether this additional screening and rejection is useful or not is a separate matter, but it’s a fact that India does practice it.

Blacklisted people, and people who have been previously denied entry

There’s also the additional motive of making it easier to enforce blacklists. Let’s say an individual has been caught overstaying or committing crimes previously (maybe even in another, cooperating country) and is blacklisted in some way. He can then be denied a visa. If the person could simply arrive in the airport, it would be different. They may catch him at immigration, but it may not be convenient to check everyone on the spot at immigration. And if a blacklisted person does show up, the country may have to pay for the flight ticket (and other administrative costs) to have him deported back to his country of origin. Neither is it a good practice to return people who have spent much time and money on their trip. Stories of such (quite possibly totally innocent) people being arbitrarily rejected at immigration and deported does not give your country a good name internationally, and does not encourage tourism. Would you want to spend your money and holidays traveling to a country that may or may not accept you when you arrive? What if you even risked having to pay your own expensive deportation flight ticked home? No matter the probability, this would not encourage tourism to that country. It’s much easier for the country to reject people during a visa application process.

Political reasons

My mother works for a Norwegian publisher. This publisher publishes, among other things, many books and magazines about geo-politics and regional politics. Some of these books/magazines have written about certain countries in less than favorable ways. After such publishings, there have been instances where people employed in that company could no longer get visas for those countries. (Even if they said they were just going for tourism.) If those countries allowed all Norwegians access without them having to apply for visas first, that would severely limit their ability to refuse entry to such people. Again, it’s much harder to turn people away at the border.

Reciprocity?

Many Latin American countries charge reciprocity fees from USA citizens on rationale that their citizens have to pay same fees when applying for visas to USA.

Russian Federation for example goes further and tries to match visa conditions both ways. Then your answer would be: they require citizens of states with high HDI to get visas because countries with high HDI demand their citizens get visas.
