Thanks
@Bryanna, makes sense, The TRV application for my in-laws is stuck in "Review of Eligibility in progress" since 9/Jun/2018 and there is no reply to case specific inquiry too(sent on 13/Jul/2018). It's been 48 Days.
No ghost emails, no acknowledgement emails and it says (Background check not applicable, bio metrics not required and medicals not required).
Should we send one more case specific inquiry?
Is it common for application to stuck for longer in "Review of eligibility?"
