Where the line falls
In the United States, the Federal Arbitration Act governs most arbitration agreements in commerce, whether domestic or international, and New York has its own arbitration statute for matters in state court. An arbitration is usually treated as international when a party is foreign or the relationship has a real connection abroad, even if the hearing takes place in New York. That label matters because international awards are generally enforced under the New York Convention, a treaty that allows an award made in one member country to be recognized in many others. A purely domestic award is confirmed and enforced in U.S. courts under domestic law alone.
How the proceedings differ in practice
Domestic cases are often administered by the American Arbitration Association or JAMS, while international cases tend to go to bodies such as the International Centre for Dispute Resolution or the International Chamber of Commerce. International proceedings commonly bring together parties from different legal traditions, so document exchange tends to be narrower than U.S. discovery, and written witness statements often replace much of the live direct testimony. Questions of language, governing law, and the nationality of the arbitrators come up more often. Costs and timelines vary widely in both settings, and neither is automatically faster or cheaper than court.
After the award
Courts review arbitration awards on narrow grounds and generally do not revisit whether the arbitrators got the facts or the law right. Deadlines to challenge or confirm an award can be short, and they differ depending on the statute and the place where the award was made. For an international award, the practical question is often where the other party has assets and whether that country will recognize the award.

That tells us which set of rules will shape the case and what should be planned for from the beginning.
