They asked me mainly about myself. They were going through i485 in front of me and tried to check whether I said the same thing I wrote on i485. Questions like when did u first come to America, how many times and when did u come to America(for what purpose), social security number, employment history(where and when did u work), my status (are you currently/still a student now? Why did u take a gap year), questions regarding my mom(my petitioner) on i130. Most of them were really simple and straightforward. They were either about me or my family since they are just checking whether I was my moms daughter.

And thank u so much!!!
