I forgot say the result,  I have received my card in last October, 3.5 months after my application.
But my wife's card was received 7 months after the application.
And I think the online application system have some problems, it runs not like we understand.  I can't check any processing status about my applications,  it's so weird that when I have got my card,  I login-in and check the status,  it still show “submitted ” and grey “review”.
I don't know how this system running. But most important is, I have  got my card as a result.
Maybe the only thing you can do is waiting.
