如果你已经给自己开了一个账号，但在给配偶开账号的时候遇到了这样的出错信息：“
It looks like you have already requested a card. You should receive your
card in 7-10 business days.”，这时你只要等一到两天再给配偶开账号就可以了，
记时从遇到出错信息开始。
I tried to open an account for my wife almost 2 months after I opened mine
and I still got this message. I emailed customer service but they didn't
understand the problem. I waited for around 48 hours and tried again and
this time it went through. So just waiting does seems to be the solution.
And the wait time seems to start from your first unsuccessful attempt.
