The US is a net exporter of oil and the country that we import most of our oil from is Canada: https://www.eia.gov/tools/faqs/faq.php?id=727&t=6
Iran has been a constant for decades, so that isn’t a factor. While Russia has been sanctioned, their oil is still being bought up at a steep discount by India and China, so those countries’ demand for oil from other sources are reduced and the impact to the oil markets are likely insignificant overall.
The process from approval to actual drilling and extraction takes longer than that. Also, we’ve been a net exporter for longer than biden has been in office.
