The author is correct, 2% to be precise. H-1 visas were introduced in 1952. In 1990, the program was split for H-1A visas for nurses and H-1B visas for others.
That one example tells, how much the author knows about the subject. In short, it is a repetition of the deep misinformation that dominates in politics and the media. That misinformation is the cause for our immigration mess.
I have studied the subject and one can find well informed articles on Medium, https://virtualagora.us/tagged/immigration. Sadly, the medium editors do not recommend my articles to the readers, but recommend to me that gibberish.
The fact that The New York Times dances around the truth on immigration similarly as Carlyn Beccia does is not an excuse.
