I received my naturalization certificate one month ago. my mom was in here. I am going to file I-130 and i-485 for her so I made an appointment for her tomorrow for medical examination. I found one post said I need wait for 3 months to apply for my mom's green card. Is it ture? I did not find any information in USCIS webpage.
thanks, If it is ture, I will cancel her appointment tomorrow,
