Hi;
How can I buy stocks for long term investing using credit card?
Note: I am not a US citizen.
Did you find the answer to your question? I'm looking for the same.

Wherever you are, you have to contact brokerage company.
They can give you even a service, when you buy and sell stocks through internet connection, using your bank account.
You can read something about how it works on the web, visiting sites of stock exchanges.
Or simple buy mutual funds

Hello Rob:

In the US, you cannot buy stocks with a credit card.
