Unless your relatives have highly sort after skills it is extremely unlikely they have been taken on as full-time Bethelites in other words signed the ‘vow of poverty’ and “Special order of full time serpents” with the small monthly stipend ( they sign this as a crafty get-out for Watchtower not to have to make the social security contributions all other employers have to).
Watchtower recently kicked out thousands of Bethelites all over the world and are too cash strapped to take on more. They do, however, take on temporary Bethelites who do full time work without even the tiny monthly stipend they used to get. These people have to provide their own accommodations and finance themselves entirely for the whole time. Additionally Watchtower does not help with medical expenses, which at least full time Bethelites used to be provided with ( unless of course the actually became ill in which case they were kicked out ).
Either way unless they have very wealthy relatives or plenty of their own investments and/or property they’re not too stupid to sell and donate to Watchtower they’ll most likely end up poor, worn-out and disillusioned.
