Cos RFE maintainence of status by principal alien

I had applied for Cos from L2 to F1
Received RFE maintainence of status by principal alien proof to be provided.
L1 lost his status in Jan 2020 and I applied for cos in Dec 2019 and filed another i539 B2 ( to bridge the gap till programme start date as per sevis.
Is there a likelihood of visa cos getting approved? as principal alien has moved back to India in Jan 2020.
i539 B2 is still pending and I received RFE for Cos to F1.

Thanks,
Roshni

Chances are low for an approval if you cannot prove maintenance of status as requested by USCIS.
