Hey @Foodman, thanks for the message.
Firstly, we have prioritised an upcoming large batch of US stocks mainly because they are the most-requested here on the forum. And also, because the work to add them dovetails nicely with fractional shares, which is launching to beta users this week.
As @SebReitz mentions, nationality declaration is indeed something which requires additional work, but it is definitely something that will be closer on our agenda following the upcoming release of fractionals and 250 more US stocks.
Thanks for the support, and stay tuned — we hear you!
