@Sm1smom I can't pinpoint the exact cause, but my visa application was denied under section 214(b). During the interview, they posed a few inquiries about my trip's purpose, my sister's citizenship status, her occupation, my own occupation, and my involvement in my father's business. However, it seemed that the interviewer had difficulty comprehending the nature of our business and the products we sell. Interestingly, they did not request any documents from me.
