Can I still contact US brokers directly? I think you need to be a US resident to create an etrade.com account, right?
If you're outside the US then etrade will direct you to the most appropriate portal for your location - e.g., if I'm in Australia, I have to sign up for an account through the Singapore portal.
Whether taking out an account with etrade gets you access to US IPOs is another matter entirely. Foreigners can generally participate (if and when your particular etrade portal is participating), but your residency is the least of your worries. The size and longevity of your account with a broker like etrade is much more important when they decide who gets in and who misses out.
