Another thing to consider:
Even if you file a lawsuit, and the court accepts to hear the case, AND you are able to serve the plaintiff in the DR with Complaint (lawsuit) papers,
AND they can either respond and defend the case, or not respond, in which case they would be in default and the judge could issue a summary judgment in your favor awarding you monetary compensation,
THEN you need to find a way to collect. You would need to locate the properties of the company in the USA (such as bank accounts or other property) because having the US judgement exectuded in DR might prove difficult, if it is not a high profile case.
