FILING ADDRESS for I-129F (K3 Visa) - QUITE CONFUSING!!

[nascar007]

Dear Sir/Madam,

1. THIS IS QUITE CONFUSING!!!! Where should I ACTUALLY send the I-129F application with my I-130 receipt notice; a), b) or c) ?

a) USCIS Form I-129F instruction says “File Form I-129F at the USCIS Dallas Lockbox facility.” For Express mail and courier deliveries:
USCIS
Attn: I-129F
2501 South State Highway 121 Business, Suite 400
Lewisville, TX 75067

b) But the USCIS website says, "Submit I-129F to the USCIS Service Center where the underlying Form I-130 petition is pending" (which is Chicago for me since I live in Colorado). This address is:
USCIS
ATTN: FBAS
131 South Dearborn, 3rd Floor
Chicago Illinois 60603-5517

c) Another website says “Use the address listed on your most recent receipt I-130 notice”. This address on my I-797 NOA1 is:
USCIS
California Service Center
24000 Avila Road, 2nd Floor, Room 2312
Laguna Niguel, CA 92677

2. One last question: Is it required to submit I-134 or I-864 affidavit support along with I-129F?

ANY ADVICE WOULD BE APPRECIATED.

Thank You very much.

Never mind... I finally found the answer myself by directly talking to USCIS personnel :-)

The petition has to be sent to TX office since this is a new submission.
Also, no need to submit any affidavit of support since I-129F instruction does not say so.
