On the immigration reform enacted by President Obama, BBC News writes (emphasis mine):
The question, of course, is just how much the US economy could benefit from President Obama's proposal, which would give an estimated four million immigrants who are here illegally a path towards legal status, as well as reforming part of the visa process that allows high-skilled workers primarily in technology fields to work in the US.
The article goes on to outline some details of this reform:
The biggest change is that the spouses of H1B visas, who had previously been banned from working in the US, will now be allowed to look for work - adding potentially tens of thousands of highly educated women to the workforce.
The changes will also allow students to stay longer.
Media coverage has focussed primarily on giving legal status to undocumented migrant workers. My question is on the second part of the reform. What are the consequences of reforming part of the visa process allowing high-skilled (technology) migrant workers to work in the USA, apart from the two changes already mentioned?
