One thing the author did not mention is that there is a huge wastage of green cards every year by US immigration authorities. That wastage compounds the problem faced by immigrants. The wastage works like this - 1. Every country is allocated an equal number of visas per year . 2. However a lot of smaller countries do not come close to utilizing their full visa allocation 3. The remaining visas can be allocated to the backlogged countries (mostly India and China) 4. The law also allows for the utilization of unused family based visas to be given to employment categories if there are backlogs. 5. However the Us government gets a fixed amount of time to make that allocation . If they do not do that allocation in the correct time period then those visas are wasted. Just as an example last year, USCIS wasted around 50K visas and this year they are on track to almost waste 85K visas. Looking at these numbers, it looks like a manufactured crisis to keep employment based immigrants in a constant state of flux so as to limit job hopping and limit their pay negotiation options.
