How do I know if the phone call I received is real?
If you're contacted by a US Green Card Office representative and are unsure of their credibility, the easiest way to confirm they are an authorised US Green Card Office representative is by asking them to send you an email.
US Green Card Office representatives will always have an @usgco.com or @usgreencardoffice.com email address. Both email addresses are completely valid and only originate from authorised representatives of US Green Card Office.
