Hi Icycool,
WP first then TRV later. Do this if your intention of going home is by 2nd quarter 2012. By that time, you have received your renewed WP.
If you cant wait, send both TRV (Seattle) and WP ext. (CPC-V). In addition to your proof of current employment, attached copies of your WP ext apps on your TRV apps. And also, make a cover letter. I guess this would be enough for a positive TRV.
To make sure, do the first. ;D
