Hi all,
I sent off my application for naturalisation in the middle of february. last week I recieved a letter enclosed with my documents but no decision. The letter stated that these were being returned for my convenience and they may need them back. It then went on to say that my case would now be looked at etc.
Is this normal? has anyone had the same thing?

It's normal. See Decision letter after return of supporting documents.
