How does a pending residency petition affect a student/tourist visa?

Question Details:

I am a recent international college graduate currently on an OPT (Optional Practical Training). My sibling, who is a US citizen and is also in the military, filed a petition for me to become a US resident about a month ago. I will be returning to my home country, Honduras, at the beginning of next month. However, I have read that having a pending petition will not allow me to acquire a student or tourist visa in the future. Is this true? If so, I will tell my sibling to withdraw or cancel the petition (Form I-130). So far we have only received a letter from USCIS, which states that they have received form 1-130 and that it is in process. If the petition is cancelled will this action have negative consequences in terms of acquiring a student or tourist visa in the future. In other words, will I be blacklisted or banned from acquiring a such visas because my sibling cancelled the petition? How long would we have to cancel the petition before it is irreversible?
