How often does USCIS release their data?
You havent mention which data. Different data are released at different times. Here are few examples:
EB Demand data which is one of the documents used for crating visa bulletin is typically released once a month. Sometimes they only release it once a month.
Visa Bulletin is released once a month.
USCIS Processing time is typically updated once a month. However is there is no change, they may not update it every month.
Annual fiscal year data is released once a year. This includes summary of all visas assigned. Further reports includes visas assigned by country, category, etc. This gives a good idea of total visas assigned per countr fo reach category.
For actual processing time of application, you can checkout the GC tracker. It will give you a latest data and which may be different from the time posted on USCIS website.
