1. Register a Delaware Inc or LLC with Harvard Business Services - https://www.delawareinc.com/. They can also act as your registered agent for $50/year.
2. Get an EIN number - you can call IRS directly at their Philly Office - 267-941-1099
instead of BoA - consider First Republic. They are very friendly to startups and have a great online system.
Also remember that getting an EIN and an ITIN (a replacement for social security number for foreign residents) is a bit involved. The most important tip - get something called a "True Copy" of your passport done withing a US Embassy in your country (e.g. http://mumbai.usconsulate.gov/notary-services.html). NOT AN ATTESTATION.
