May an F-2 visa holder marry inside the US with a US citizen/green card holder without ending the previous marriage?
<p>If someone with F-2 visa status comes to the US, then wants to marry with a US citizen/green card holder, should he/she ends/gets divorce of his/her previous wife/husband even if their marriage happened outside of the US and they both aren't US citizens/green card holders?</p>

<h2>Only the currently unmarried may lawfully marry in the US</h2>
<p>US laws generally prohibit a marriage if either person is currently in a valid marriage to a third person, whether in the US or anywhere else. If a current marriage is valid it must be ended by divorce or in some other lawful way before a valid US marriage can occur. Marrying in the US while already married to another person is the crime of bigamy, and will also render the later marriage invalid and void.</p>
<p>All this is true regardless of immigration status, it would be true for citizens, green-card holders, holders of any visa type, and undocumented people. No one may contract a marriage while currently married to someone else.</p>
<p>I believe this is true in all US states and territories.</p>
<p>Committing the crime of bigamy could possibly have negative impact on the immigration status of a non-citizen, in addition to potential criminal penalties.</p>
<p>I am not sure why you would think it might be OK to proceed with such a marriage without first obtaining a divorce, annulment, or other lawful termination of any existing marriage, inside or outside the US, but it is not.</p>
