Thanks Hani for the link. Actually I have already gone through that information. Just curious about the delivery times of USPS. My wife is taking up follow up from her's medical university on daily basis and as of now, they have not received any ecfmg. Agent at MCC wrote us that the concerned document was sent for verification by ecfmg to her institution on June 14 and regular mail service of USPS was used as courier.Dear salmanzahidi,
the following link provides information regarding the different processes timelines:

Best of luck,

Unfortunately regular/standard service of USPS is pretty slow and it may take up 3-4 weeks for the document to reach Karachi though I am not sure about it. Already 12 days have passed.
