Visa Services, U.S. Embassy London

I came to the United Kingdom for a short holiday, but ended staying here for longer than 12 months. I have a green card. Do I need anything else to return home to the United States?

If you have been outside the United States longer than 12 months or two years if holding a Re-entry Permit, you will require a new immigrant visa in order to return to the United States.  I suggest that you visit the Embassy website for information on the options available to you. 

I have recently traveled to the United Kingdom and while here, my green card has been stolen/expired. What can I do?

If you have been outside the United States for less than 12 months and your Permanent Resident card has expired or has been lost or stolen, and you are not in possession of a valid Re-entry permit, you may apply for a transportation letter to return to the United States.  A Permanent Resident Card cannot be extended or reissued outside the United States. We suggest that you call the Operator Assisted...

I have a US immigrant visa (green card) but have been back in the UK for nearly six months now. A friend tells me that I have stayed outside of the US for too long and may not be allowed back in. Is this true? And how long am I allowed to remain outside of the US for, if I have a green card?

A lawful permanent resident may apply for admission to the United States using his/her Permanent Resident Card, provided he/she has remained outside the United States less than one year and has maintained an unreliquished domicile in the United States.  If you wish to remain outside the United States for longer than 12 months, and you have sufficient cause to do so, you may apply for a Re-entry Permit. ...
