In this article, I will provide an example how you can transfer fund to your new TD Ameritrade account via wire transfer from overseas to US. Beware that the information is accurate at the time of writing of this article. You should always refer to the information provided to you by TD Ameritrade before actual fund transfer.
You can wire your money via Citibank or CIMB Bank if you are located in Malaysia.
Please be aware that your fund transfer may be rejected even it is a small error in your form. The fund returned to you will be lesser than you sent initially after currency conversion both ways as well as processing charges from both US and your bank. So always double check your information before transfer your money.
I am using CIMB transfer form as example.
