I don't like his stance on H1-B visas.
The system is totally abused, and Trump has, for the most part, seen little reason to fix it.
Massive corporations use this loophole to essentially hire slaves for lower wages than Americans to lower maintenance costs. Your company fires you, they put up ghost job listings with impossible requirements to fill your old position so they can claim there were no qualified American applicants, and then apply for an H1-B for the man with 4 PHDs and 15 years of experience in blockchain AI (who will conveniently work for only $50,000 and doesn't require health insurance). Now you apply thousands of places, hoping to get a good job. But, they're all being rejected because the companies never intended to hire anyone in the first place; it was all an automated rejection process so they could get cheaper H1-Bs processed. There are hundreds of thousands of good paying jobs that Americans want to do, but are completely blacklisted from in the job market because the system benefits screwing over hardworking Americans by importing their competitors.
