In addition:

The President’s proposal attracts the best minds to America by providing visas to foreign entrepreneurs looking to start businesses here and helping the most promising foreign graduate students in science and math stay in this country after graduation, rather than take their skills to other countries. The President’s proposal will also reunify families in a timely and humane manner.

How onerous are the conditions for the path to legalization?

Undocumented immigrants must come forward and register, submit biometric data, pass criminal background and national security checks, and pay fees and penalties before they will be eligible for a provisional legal status. Agricultural workers and those who entered the United States as children would be eligible for the same program.

Individuals must wait until the existing legal immigration backlogs are cleared before getting in line to apply for lawful permanent residency (i.e. a “green card”), and ultimately United States citizenship. Consistent with current law, people with provisional legal status will not be eligible for welfare or other federal benefits, including subsidies or tax credits under the new health care law.

A positive: Addressing humanitarian concerns

The proposal streamlines immigration law to better protect vulnerable immigrants, including those who are victims of crime and domestic violence. It also better protects those fleeing persecution by eliminating the existing limitations that prevent qualified individuals from applying for asylum.

Did anyone catch this? Obama wants to increase penalties for drug offenses that involve drugs coming in from other countries:

The President’s proposal creates new criminal penalties dedicated to combating transnational criminal organizations that traffic in drugs, weapons, and money, and that smuggle people across the borders. It also expands the scope of current law to allow for the forfeiture of these organizations’ criminal tools and proceeds. Through this approach, we will bolster our efforts to deprive criminal enterprises, including those operating along the Southwest border, of their infrastructure and profits.

How much greater can the penalty be? If the drugs someone brings in from another country can be tied to a cartel, and life in prison without parole isn't high enough, what's left? Life plus cancer?

Obama also proposes increased penalties for other crimes:

The President’s proposal creates tough criminal penalties for trafficking in passports and immigration documents and schemes to defraud, including those who prey on vulnerable immigrants through notario fraud. It also strengthens penalties to combat human smuggling rings.

This sounds like the work of crime warrior Joe Biden. He can never resist a chance to increase penalties.

There's also this, in which "streamlined" seems to mean a shortcut around due process:

Streamline removal of nonimmigrant national security and public safety threats. The President’s proposal creates a streamlined administrative removal process for people who overstay their visas and have been determined to be threats to national security and public safety.

Why wouldn't Republicans love this plan? It sounds like they wrote most of it.
