Need some assistance. I am an EU national been living and working in the UK since 2012. My Spouse is a non EU and came to the UK in Sept 2015. I have applied for his residence card eea2 application but haven't heard anything, its been 4 weeks now. I paid by postal order
EEA2 Application sent: 10-02-16
HO Received: 11-02-2016
Biometric Letter: Not Received
COA: Not Received
Status: ???

We sent the application via royal mail special delivery. Can anyone advise how long does it take for the Biometric letter to arrive as I am aware that without the biometrics letter we will not receive the COA letter.
Regards,
Leo
