How to apply for an F2B immigrant visa?

After paying the visa fee, parents should also be informed to apply for financial guarantee, and then send it to P3, fill out the I-230 form and send it back, and then send it to P4 after 3-6 months. There will be a detailed list in P4' s bag, telling you what information you should bring in the interview. So I guess you won't come to America until next May or so.
