It would be very helpful if you can answer some questions:
1) For
Tradestation did you apply for Options? What about
crypto?
2) Did you fill a W-8BEN or a W-8BEN-E ?
3) Besides the W-8 you only had to attach the Article of Organization, Operating Agreement, Passport and proof of address?
4) Is the Proof of Address for the company or for me?
5) What did you use as the Principal Business Address? In IBKR they didn't accept the Registered Agent address in US, so I had to arrange a proof of address in my home country.
6) Did they ask for other documents after applying?
