Hi, here's an answer I got from my requesting institution (a New York based bank) who says they'll accept the following:

1. A New York Correspondent bank referenced in the foreign bank’s guarantee stamp.
2. An overseas branch of a United States Bank or a member firm of the New York Stock Exchange firm referenced in the foreign bank's guarantee stamp.
3. A correspondent branch in the United States, which is referenced in the foreign bank's guarantee stamp

You can check with a major brokerage firm like Smith Barney, Edward Jones etc… For a bank institution you can also check with Citigroup

I am only doing a name change on the stock holder (me), and not any transfer of ownership so there is less liability involved.

cheers,
