Question: how long does it take a package to get through isc new york?
Answer: Short answer: ISC NY hasn't even received your package. The CBP (Customs & Border Patrol have it if it's been more than 2–3 days. And they'll hold it as long as they want to hold it, and that really stinks. If it's been more than a few days, you'll want to check out this link from the CBP website.
