You have to file at NSC. You could get some success trying to file on a specific day, so that the case gets forwarded to TSC. Read at immigration-law.com:
06/30/2006: Distribution of I-140 or I-485 Filings Between NSC and TSC
The newly released Bi-Specialization Procedural Change announcement indicates that the work loads are split between the two Service Centers either on the alternate date basis or each daily basis depending on the volume of petitions/applications the Nebraska Service Center receives on a specific date.
From April 1, 2006 until the last few days, the I-140/I-485 incoming cases had been split between the NSC and TSC by alternating each day. This practice has created so-called NSC-Day and TSC-Day and some practitioners carefully selected the filing date such that their cases went to one of these Service Centers. This practice was confirmed by the Director of Service Centers Operations at the USCIS HQ at the San Antonio AILA National Conference. However, in the NSC-NAFSA Q&A minutes, the new Acting Director of the NSC disclosed for the first time that one-half of the incoming cases were shipped to the TSC everyday. This information certainly conflicts with the statement of the Director of Service Centers Operations at the HQ. People will soon find out which source of information is correct.

rollingstone said:Folks,
I am new to this forum, so apologize if my question sounds stupid.
I would like to know how the decision is made where to file I-140 - does the center get assigned by USCIS or can you choose where to file?
Thanks in advance.
