It goes by your state of residency (the person referring), so I believe Texas is not eligible (the reason is state laws regarding time-share sales). Check with your Guide tho to make sure.
In case you are not eligible, you may want to have a pal in an eligible state refer your referral in your place, get the bonus and send you the after tax portion (I have done this with some of the folks I have referred).
The bonus is payable to the DVCer referring in the form of a Disney Rewards Card, payment on your maintenence fees (usually our preference), credit towards an add-on or a donation (in your name) to the American Red Cross or Give Kids the World (our other preference).
I hope this helps.
