Something like: "keep the situation as is".
I guess there might be many options to convey the required meaning, however, I also assume there is a phrase that is more commonly used?
I was thinking of "sicut est" or "ut est", but I'm not sure as the usage of "est" is so appropriate here. maybe better "sicut id est".
It might also be usful to contrast the phrase "as is" with the phrase "like that" which, to my understating of English, don't have the same meaning. "like that" implies comparison to something else, where "as is" is "comparison" of something to itself - to it's own current state.
