Default How to remove Input Method icon in notification area

I'm using the Google Keyboard (only keyboard I'm using) on my Nexus 7 with 2 input languages, my native language and English.
When the keyboard pops up I have a icon in my notification area to select input methods.
I want this icon removed. I do not need it but I can't seem to get rid of it.

Any tips?
