My husband lied to me saying that he was never in another country accept his hometown, but later I found out he was illegally in other countries and married to another woman in another country and legally in that country? Can I deport him?

No, you can not deport him, you can file for divorce (or annulment if he is still legally married in other nation) But just lying to you about where he lived is not really grounds for anything.

Depending on his immigration status, you can report him to immigration who will decide if any of this was a violation to cause him to lose his status
