I think it takes some time for them to get back at additional docs requested... I submitted mine 2 months ago and they haven't updated it, still says from my acct: 'your action is required'; meanwhile if you read the additional docs part it says they've receive it... I was also wondering how long will it take for them to review the docs they asked to be submitted again... it's so frustrating and exhausting but can't do anything but wait... I'm not even asking for much, just wanted to get my eligibility letter and open work permit soon...Has anyone submitted the requested forms and got any further updates?
