Hey! We finally got our bio letters so @SusieQQQ you were completely right As I see we need to fill out the second page of bio letters. Since my husband swapped first and last names in i-485 I'm wondering whether writing them down in a correct way in the bio letter could cause any prob since it will differ from I -485. But We will tell the technician about swapped names anyways so that they could make a note for the background check.
