Are foreign ETFs subject to the same PFIC rules as foreign mutual funds?

Yes. A non-U.S.-domiciled ETF is generally a PFIC just like a foreign mutual fund, because it is a pooled foreign investment vehicle earning mostly passive income. This surprises immigrants who assume ETFs are automatically safe. Buying, say, an India-domiciled or Europe-domiciled ETF exposes you to the same punitive excess-distribution regime and Form 8621 filing as a foreign mutual fund. The reliable way to get international or home-country exposure without PFIC problems is to hold U.S.-domiciled ETFs and mutual funds that invest in foreign markets; those are ordinary U.S. securities and never PFICs. So an India-focused ETF listed on a U.S. exchange is fine, while the same strategy bought on a foreign exchange is a PFIC. When in doubt, confirm the fund's country of domicile, not just what markets it invests in.
