Dual-status filing in the USA - which mailing address to use

So, I decided to file a dual-status this year. After going through all the paperworks, now it comes down to the mailing part.

From pub519 ch6, "if I am a resident alien on the last day of the tax year...file return to Austin, TX." But it is not clear that should I file both 1040 and 1040NR to Austin, TX? or should I still file another copy to Fresno, CA since I am staying in Washington.

Thanks

File to Austin as you are now a resident alien if you're filing dual-status to move your tax home into the US.

Thx for quick reply, Steven, much appreciated
