Over 10% of the US population has no access to concealed carry. This is in part a way to knock those barriers down when Californians will be able to carry in CA with an OR or NV non-resident permit as this bill allows.
I think you have been misinformed. "H.R. 822 allows for carry in any state except for Illinois and the state of ones residence." That is from http://gunowners.org/a111411.htm.
In part, this bill appears to be an attempt to repair flawed judicial reasoning, in particular, corrupt application of the Supreme Court's Presser case. The Presser case says states may NOT infringe the RKBA. Federal courts have uniformly applied the Presser case for the opposite, as allowing states to infringe the RKBA. Total, absolute, abject corruption by the Courts - and it is easy as pie to see for anybody who looks.
Back to the subject of the post, see HR 822 - National Right-to-Carry Reciprocity Act of 2011 for links to the text of the bill and Congressional actions.
If your only reason for supporting the law is to give residents of (for example) CA the ability obtain an out of state license so they can carry in CA, then you should be neutral toward or against the bill, because it does not enable that function.
