My mom filed and was approved with 245i through her sister's petition. My dad was not included in the petition (for some reasons) and both of them overstayed their B2 visas since 1998. Now I got my Naturalization and passport (thank God for this forum's help!), I want to file a petition for them by myself. Is this just a case of a straight filing only since they are presently here in the US or do you see any complications in this case that we need to get a lawyer to take care of this? What's the difference between an ordinary parent petition and one with 245i? Do they issue I-94 with 245i? I was asking my mom but she doesn't know what it is but she has all her paperwork and she lives in TX and I live in CA.
