My girlfriend is Romanian and we met 2 years ago while working in Kuwait. We have since left Kuwait and come back to the US. She is here on a Visit Visa at the moment and we want to get married. What are the requirements for us to marry? Do we still need to get a K-1 Visa? Thank you.

If her visitor's visa is close to expiring, yes you should have her apply for a K-1. Even after you are married she does not automatically get a green card. It can take several months for the green card application based on marriage to be accepted.

USCIS will review the file and during this time she must keep a legal status by either getting an extension on the visitor's visa, a K-1 visa or leaving the coutnry until it's processed.

How Do I Bring My Spouse (Husband or Wife) to Live in the United States? (http://www.uscis.gov/portal/site/uscis/menuitem.5af9bb95919f35e66f614176543f6d1a/?vgnextoid=3e6c96981298d010VgnVCM10000048f3d6a1RCR D&vgnextchannel=4f719c7755cb9010VgnVCM10000045f3d6a1 RCRD)
