Is living in a Jewish community an absolute requirement of converting to Orthodox Judaism?

I spoke to a rabbi and then a recent convert about conversion to the Jewish faith, and the convert I spoke to told me that no Orthodox rabbi would convert me if I didn’t live in a community where I was walking distance from shul, as to make it possible to properly follow Shabbat by not driving a car to shul. It’s not possible for me to live in a “Jewish community,” as I’m a freshman and live on a college campus. Granted, I am walking distance from the campus Chabad. However, I don’t know if that fits the requirements, or if I would be in a position where I’d be able to live in a Jewish community after my undergraduate studies, as I’m sure my conversion would take longer than four years.
