My visa case status f2b

My case was just approved f2b category and my case is was filed on 11th jul 2017. Now how long should i wait to get welcome letter can anyone tell please ???

With backlog it hard unless they pass immigration reform recapture unused visa jumpstart that Congress introduced or with bbb Build back better it which’s might both not happen because of jo menchin and republicans doesn’t want title 42 to be over so it less likely to immigration reform to happen
