I am an OT practicing here in the US and came from another country. I graduated with BSOT and had an OT VOLUNTEER work for 2 years in an adult setting back home. Would that count as a part of the 5 years experience? And from that 2 years, I was not yet licensed OT for the first 6months.
GENERALLY speaking, for EB-2, there is no requirement that I know of mandating paid experience. Volunteer experience could potentially be used.
