Think it would need to be >850 if it is an international applicant.
I was an international applicant, but from Canada. I'm not sure if the higher requirements are because international school systems are too different from the US or if it's because it's more competitive as an international student (and thus there's a higher score standard). If it's the former then my point here is moot!
My PGRE scores were 640 (2009) and 690 (2011) and I was still able to get into some top ranked US astronomy departments (namely Cornell and U. Washington at Seattle). However, these scores might (or might not) be a part of the reason why I didn't get into UC Santa Cruz, UC Berkeley, or Harvard.
