Filling profile for visa interview. VERY URGENT PLEASE

[diegoe]

My mum filed for me under the F2(b) category for immigrant visa in 2011. Two years ago she became a citizen. Now I have been scheduled to profile and book an appointment with the US Consulate. On the Confederate. secure. Force. com/update data. I am confused as to whether I should select F(1)-us unmarried son or daughter
OR F22-Child of lawful alien resident. Would it matter if I select F1 even though my visa category is F2b? As I can't find F2b. Or should I select F22? Please I need clarifications. Thank you
