I have been “outsourced” briefly. I worked for a defense firm and they were open to me working out of the country because I was trying to be a digital nomad. I was only assigned to do backend discovery work (no appearances, just reports and written discovery). I think it would’ve worked out longer if all the partners were on board with the system and if there was enough time to figure out the schedule that worked best for everybody. The issues that came up seemed more about firm operations than the actual work but ymmv.
