Johnny,
Good point and I for one like the point system as it will give the vast majority of legal permanent residency visas and GCs to immigrants based on the factors such as age, education, skill and English proficiency. On the other hand, the current system gives visas based on (for the most part) foreigner's family ties to relatives already in the US.

I don't know for sure, where Obama's current stand is on the issue but I think there's a trade-off as going for the point system will make legalization of the status of the illegal immigrants ALREADY in the US far more difficult. So the comprehensive immigration plan which Obama is committed for will go begging. You cannot make two contradictory demands at the same time. And I suspect that's why Obama is against the point system, if he still is that is. Even if he still is against the point system, it does not and will not stop the US from welcoming skilled manpower, as it is doing now, coz otherwise its economy will never prosper.

I think, in the long run, once the status of the illegal immigration is sorted out, irrespective of who is going to be the president, US is going to opt for the point system. It's just a matter of time as I see it.
