I agreed with Jackolantern. There was operations intructions as stated in service policy which states it doesn't effect the IR of USC.
I found these documents while searching for similar qns. that I posted yesterday. Btw some punks flammed me giving BS answers saying all parents on visitor visa and filing for AOS in US will result in denied of I-485 because of preconceived intent to immigrate. I have no idea what they were smoking. if you search the forum, I haven't found single post saying their parents AOS was denied just because they came on visitor visa and later filed AOS.

"Long standing Service policy (Operations Instruction 245.3(b) provides that,
If the evidence clearly establishes that the visa was obtained by fraud or misrepresentation, the application shall be denied, unless the applicant qualifies for a waiver of that ground of excludability pursuant to section 212(i).
However, this same instruction provides the following policy for immediate relatives of United States citizens (spouses, parents, and unmarried children),
In the absence of other adverse factors, an application for adjustment of status as an immediate relative should generally be granted in the exercise of discretion notwithstanding the fact that the applicant entered the United States as a nonimmigrant with a preconceived intention to remain. Matter of Cavazos, Int. Dec. 2750(BIA 1980) clarified and reaffirmed. Matter of Ibrahim, Int. Dec. 2866 (BIA 1981).
On the other hand, if there is no clear evidence of fraud or misrepresentation, the mere fact that the applicant had a preconceived intent to remain in the United States permanently will not usually result in the denial of their application for permanent residence if they are classifiable as an immediate relative of a United States citizen.
