Xiaobaitu, Pijiang: RFE for dependent's I-485

My I-485 has been pending since December 2004. My hu*****and is the main applicant (NIW) and he got his green card in September 2006. Last week NSC sent me RFE for his current employment letter. Actually, he was self-employed for quite a while. To answer this RFE, he found a small firm in the same working field as his NIW application. His employer issued an employment letter saying that his starting date was recent.

Will this letter affect my I-485 application or am I worrying too much?

Thanks a lot!
