I am from... to help...

I can find no fault in them working in other countries waiting for thier US Visa to come through.
Their goals is working in USA, and doing anything and everything to reach that goal is what they are doing, and I can find no fault in that either

USA is known as the Land of Opportunity for a reason.

The US Embassy in Manilla issues about 150 Visas to USA per day, I would find a way to get to USA if I was a looking to migrate to a certain country.

And that's the problem: for some reason, you just don't get it.
Canada is not part of the United States. Canada is a different country.
When people go to Canada--and use it as a "stepping stone" to the US--it is insulting to the people of Canada.
Very, very insulting.
So, if you want to work in another country while you are waiting to go to the US, you should pick a country where the people won't be so offended by your behavior.

If someone immigrates to USA and then wants to move to another country to work, I have no issuses with that.

It's someone trying to do better for themselves. They are not indentured servants.

Well, we'll just have to agree to disagree, I guess.
Apparently you don't "find fault" or "have issues" with anything anyone does as long as what they are doing is legal. You prefer to not consider the socio-cultural implications of their actions, though--the bad feelings it causes in Canada when using their beautiful country as a mere stepping-stone.

Maybe it's a cultural difference between your country and Western countries. Maybe in your country it is entirely acceptable to do whatever you can to get ahead, to trample on the feelings and customs of others as long as YOU get what YOU want! However, in Western countries that type of attitiude is considered selfish. Maybe that's why you appear as though you do not understand what others are saying--because it's a cultural difference. Maybe one of the reasons for the bad feelings directed at foreign nurses is this difference in perspective.

So no, not everybody in the States is happy when they are used as a stepping stone, people got the greencard and left the emloyer that sponsored them, you don't think that employer is happy, eh?
