A. If you are in the U.S. and buys the foreign stocks via your stock brokers, you will need to file IRS Form 8938 to report these assets.
To avoid such paperwork, you have two alternatives to buy foreign stocks:
1. Buy ADRs
American Depositary Receipts (ADRs) are foreign stocks that are listed in US stock exchanges, any U.S. investors can buy and sell them, in U.S. dollars.
2. Buy ETFs/MFs
