Status "received" to CO contact?

Hi guys!

Gaano katagal bago icontact ng CO if yung status sa 'next steps' portion ng application changed from 'required' to 'received'?

Does that mean CO is already looking at my application? If so, from experience in how many days or weeks were you contacted by your CO?

BTW, I front loaded all my documents including medicals, police and form 80.

Thank you!

Hi retrolife, anung type ng visa you applied?

same ang question ko hehe... nagchange na din yung sakin from required to recieved pero wala pang email CO
