Histologic recovery of small intestinal mucosa is assumed to occur within 6 to 12 months after starting a gluten-free diet, simultaneously with clinical remission. Surprisingly, follow-up data on small intestinal recovery in celiac disease are scarce and contradictory.

This particular study only looked at 2yr and 5yr follow up periods, and villous atrophy can persist even this far out in some people. I can't find any study that looks for recovery of villi any earlier than 6 months time.
Yet, I know... the recommendation is to eat gluten right up until the biopsy... despite the fact I'm coming up short on anything to support that.
Well, at least I found the recommendation from an authoritave source:
University of Chicago Celiac Center

Are you scheduled for a biopsy? Are you eating gluten?
Any changes in your diet can affect the accuracy of your biopsy results. It is necessary for you to be eating gluten every day for at least 4-8 weeks before the procedure. If you are scheduled for a biopsy and are not eating gluten, talk to your doctor about what is necessary to obtain accurate results. If you have a biopsy and have eaten gluten only a short time before the test, you and your physician will not know if a negative test result is accurate or due to your diet.
