lol...I can't stop laughing at the comments. US is not doing this to favor these people with STEM degrees. US is doing this to give itself an advantage over other nations. Every nation tries to keep the best and the most demanded people and thats what US is trying to do. They don't need more sociologists, economists or business majors. There are plenty of them out there. They need more people from IT sector, math n science. So, all they are doing is trying to address the needs of the nation. It was mostly the IT sector that lobbied all the way to get these extensions and here they are....
