how cooked am i?

i’m a fall ‘24 aspirant going to a well ranked school in San Diego (always been my dream to study there and experience California). i started filling out the ds160 form and have been tensed and anxious since stumbling across the immediate relatives question.

my brother is a h1b visa holder working at a company in California, LA to be specific. albeit i wouldn’t be living with him, it’s possible that the visa officer would ask questions about my brother’s status and everything. i know i’m not the first person to be in this sort of predicament. but, my question is would i be straight up rejected in this situation or do i stand a chance, if so what are my odds?

any tips and advice would be highly appreciated to bring me out of this spiral!
