Immigrant visa? What is that? I think the conversation is focused on the US. I'm a native-born US citizen, but my impression is that for those who get an H1B, they can apply for a green card and eventually citizenship. However, the path for many is fairly long. Perhaps you are confusing the H1-b and the J-1?

You can read about the difference here[1]. H-1B is a temporary visa and does not entitle a holder to permanent residency. In some cases it's possible for a H-1B holder to be granted permanent residency because it's a dual intent visa, but that merely permits the holder to desire to immigrate. By contrast a tourist visa would be denied to a visitor who expressed the desire to stay permanently.
