This is the bill that tried to reform immigration. It was proposed in 2021.

Here’s how Forbes describe its provisions:
”In February 2021, the U.S. Citizenship Act (H.R. 1177), developed by the Biden administration, was introduced in Congress. The bill contained many immigration provisions and would have put an end to the employment-based immigrant backlog within 10 years. It included a higher annual green card limit, eliminated the per-country limit, provided permanent residence for those waiting with an approved immigrant petition for 10 years and excluded dependents from being counted against the annual limit. (See here.) It also would have exempted individuals with Ph.D.s in STEM (science, technology, engineering and math) fields from numerical limits.”
And, yes, the opposition was a Republican thing. Again, Forbes:
”Due to GOP opposition and the 60-vote filibuster threshold in the Senate, the U.S. Citizenship Act turned out to be a messaging or placeholder bill that did not move in Congress.”
