Two weeks without a recruiter response is not automatically unusual, especially during busy recruiting periods. A referral can enter the same screening queue as other applications.

If you have a recruiter contact, a short professional follow-up is reasonable. You do not need to ask the referrer to intervene immediately unless they specifically offered to help with follow-up.

Keep the message simple: confirm your continued interest, reference the application or referral, and ask whether there is any additional information needed. If useful, this guide on consulting referral guide gives more detail.
