How can i subscribe IRA online? (or on any brokerage)?

Question

I m from Singapore, and i wish to do it locally without any foreign exchange

Answer 1

What's the purpose of someone from Singapore trying to start a US IRA account? I don't think someone who is neither a resident alien or citizen can even invest in such an account. Do you pay US income tax? If not then there is no point, IRA is just for US retirement tax savings.
