Can I use my ITIN instead of an SSN for a job application?

I'm currently living in the US, and I'm in the process of getting a green card. They approved me, but I still have to wait one more year before I get my papers. But I have a problem. I'm not allowed to leave the U.S. before I get my documents, because if I do then they'll deny my request and cancel... show more I'm currently living in the US, and I'm in the process of getting a green card. They approved me, but I still have to wait one more year before I get my papers. But I have a problem. I'm not allowed to leave the U.S. before I get my documents, because if I do then they'll deny my request and cancel my status. So right now I don't apply for an SSN, but I do have an ITIN. I need to get a job, but almost all companies ask for an SSN. Can I use my ITIN instead? It's still a tax payer number and it's perfectly valid on checks. And when I get an SSN, all the info from my ITIN will be converted on that number instead.
Update: I'm Polish, actually. I tried getting a work permit but they won't let me until I get my documents. Okay this country makes no sense. They tell me that I'm forced to stay here until I become legal but until then I can't work, can't get an apartment, can't get a drivers license. . .I... show more I'm Polish, actually.

Update 2: DAR, you have no idea what you're talking about. I TRADED my "visitor VISA" for a greencard. Having a VISA doesn't even have anything to do with being illegal or not, anyway. The government doesn't give "visitor VISAS" to people who want to be legal. A visa is a document to be able... show more DAR, you have no idea what you're talking about.

I came here on my visa, but since it was currently being used as a tourist, I had to trade it.
