This is great news for employment based immigration. It makes the system FIFO and helps American workers by reducing the number of people waiting perpetually in line for a GC. This way people stuck in the backlog can move jobs easily and accept promotions which helps avoid depressing wages. This bill also strengthens protections for H1B to reduce fraud.
The inability of foreign workers to move jobs easily constrains labor supply, thus pushing wages higher. I fail to see how any of this is good news for the American worker. Stop me if you’ve heard this one before.
