You were only allowed to stay in the U.S. until 3/8/11. By remaining beyond that date you were in violation of your immigration status. This violation will be looked at every time you seek to return to the U.S. and particularly when you apply for a new visa and may prevent you from returning. If you attempt to return under the visa waiver program, you may be denied entry and issued a removal order that will bar you for 5 years from returning or receiving a visa. You may still be issued a new visa if you disclose your overstay to the Consulate when applying and it will be within the Consulate's discretion to grant you the visa. The Consulate cannot grant you any visa for 3 years if you remained in the U.S. for more than 180 days and subsequently left. The bar will increase to 10 years if you stay for more than one year past your authorized stay.I recommend consulting with an experienced immigration attorney to discuss your relationship with your girl friend. If she is a U.S. citizen and you are determined to building a life together, you might be able to regain legal status IF you do not leave the U.S. I strongly recommend seeking the consultation before you remained in the U.S. for more than 180 days past 3/8/11.
