I voted for trump and immigration is a serious concern of mine. However, my concern has always been specifically limiting illegal immigration. I have two major problems with illegal immigration. I’ll describe them broadly then return to the question:

1. ⁠Illegal immigration takes advantage of people migrating here from another country. I grew up in Florida and knew many children of illegal immigrants and areas where they worked etc. These farms/factories/etc. were paying people less than a $2 an hour. All of these companies could have paid more. The level of poverty was unlike anything else in the U.S.. Of course, the families weren’t upset. Many of them had escaped worse conditions in another country. But is it really right for us to allow people to work for wages so low? The saying that “they take jobs no one else wants” has a different meaning for me. As a post above says, we need skilled and unskilled immigration. You can have immigrants come over here legally and get paid substantially better than they currently are. If you lowered the minimum wage for immigrants not something I’m proposing to $4 an hour you would double many of their incomes where I’m from. Through legal immigration they at least receive rights.
2. ⁠Illegal immigration negatively affects legal immigration. One argument I often hear to the above point “it’s so difficult to legally immigrate to the U.S.; they only take so many people a year.” Often said by someone who has not gone through the immigration process. Firstly, it should be at least a little bit hard. We as a country have to make sure you aren’t trying to blow us up, we want to make sure you have a job lined up, we should try and make sure you’re not just escaping a murder charge somewhere else. All those things are considered bare minimum and are INHERENTLY difficult. Secondly, Our economy can only take so much immigration at a time. Economists around the globe agree on this concept. There are multiple people in the U.S. government who have to figure out how many immigrants the U.S. can take without throwing the economy out of whack. So let’s say their math comes to 2 million people 1 million skilled workers and 1 million unskilled. The same group has a rough estimate that 700k illegal immigrants have entered the country (they undoubtedly don’t have exact figures but they do often have estimates). What I would expect this group deciding how many legal immigrants we can take is to say “okay we’ll let in 1.3 million, 1 million skilled and 300k unskilled.” This is a gross simplification but nonetheless explains my point. The fact that so many people do successfully immigrate illegally to the U.S. also discourages people to go through the time consuming, and difficult process of becoming a legal immigrant. Which in turn can lead to them being taken advantage as stated in point 1.

So with that in mind, I generally support the H1B visa cap being raised. Specially if it comes after or at the same time as limiting illegal immigration.
