I am US citizen filed GC for my dad and received I-797 C on june 2018. My dad interested to come early next year( he has 5 yrs valid visit visa). Can we adjust the status when beneficiary in US

i found online .......


If your parent gained legal entry into the United States (through a visa or other means), then later decided to apply for a green card, he or she is eligible to file an I-485, Petition to Adjust Status, at the same time as the I-130 application. This will lead to immediate processing of the green card, without the need to wait for approval of the I-130. (But be sure your parent does not or did not use a tourist visa, visa waiver, or some other visa as a way of gaining U.S. entry with the actual goal of adjusting status. That would be a misuse of the visa, and could lead to the green card being denied based on visa fraud.)

last sentences within parenthese scared me . Please advise.
