It was recently announced that after Sept. 1, Jehovah’s Witnesses will again engage in house-to-house canvassing.
Because of ongoing concerns regarding COVID-19 / Omicron BA.5, some witnesses may choose to wear masks when approaching your door. But even so, if your circumstances permit, meeting them outside would be prudent.
They have been advised to maintain a “respectful distance,” so please don’t be offended by that. 
During the worst of the pandemic, all meetings and conventions were conducted via Zoom, an internet teleconference app. The only approved witnessing done then was by phone or U.S. Mail, and a few witnesses may continue using those means to try to contact you.
