Hi, has anyone used their investments or annuity to create a business to hire yourself for the workcation dtv? If so how many months did you set up your business prior to applying? (If American would a dba certificate suffice or should I set up an LLC)

I have a stable annuity and would like to use that via a business instead of doing a soft power visa. (We prefer this bc although we want to take language classes we don’t want to be tied down to one area of the country for those classes)
