Hello
I am living in Spain for 10 years and have tarjeta de residencia LARGA DURACION. I am going to file an application for nationality this november (november 2012 I've got appointment for nationality application ) .At the same time , i ve got a better job contract in Germany and i am thinking to change my residence card to TARJETA DE RESIDENCIA CE .
The confusion is that

Would it effect my nationality application ?
Should i first file a (nationality) application and then change my residence category to Tarjeta de residencia CE ?
or what should i do ???

Hopefully you ll guide

Regards : )
