What are my chances of getting through F1 Visa interview?

I’ve got an admit from Fitchburg state Uni (MS in CS) & didn’t apply for any other as my Brother in law & sister leave nearby the uni. My Brother in law is in H1b & got EAD. My sister is working too. I’m afraid of getting rejected due to 214(b) potential immigrant issue. Please help me out. Should I tell about them or conceal? I’ve 3 yrs of work ex in IT.

Thanks

Stop over thinking and just tell the truth.
