is my marriage leagal if just finding out my husband has another wife in a different country

No, if your spouse was already married at the time of your marriage, then that is bigamy and your marriage is void.  However, you may want to seek an annulment in order to clear up the public records and sort out any property that you have.  If you want to stay married to him, then he should divorce his first wife and then you should get remarried to him. This answer is given in accordance with the laws of Virginia and may not be applicable in any other state.  It should not be construed as legal advice, as that would require a more thorough analysis of all of the facts involved in a specific case.  If you need further information or assistance, please feel free to contact my office for a consultation.
