Vist US on B1/B2 visa while awaiting CP

#1
My I-140 was approved a few weeks ago under EB1A category. We live outside the US and are awaiting consular processing to begin. Based on the current information it seems that consular processing can take anywhere from 6 months to 12 months. In the meantime, I will like to travel to the US in June for an important meeting on my B1/B2 visa that is valid until May 2020. Is this visit technically possible? What are the practical implications?
