Very Urgent(New Topic) : Family Sponsorship, Worked Remotely

[shakeel7]

I came Canada in March 2007 and stayed as above till today:

Canada : Mar. 2007 - Sep. 2009 (6-months).
Pakistan: Sep. 2007 - May. 2009
Canada : May. 2009 - Currently living in Canada, and sponsored my wife in July. 2009

Worked Remotely from April. 2007 - June. 2009 and also filed Tax Return of 2007 & 2008 and Option C printout of Tax Year-2008 also included with my application. I worked as independent sub-contractor in IT field from April, 2007 - June, 2009 and attached letter from that company with sponsorship application.
But didn't mention on Company Letter that I had Worked Remotely.

Now, CHC Islamabad issued a letter to my wife stated that
"As per information on your application your sponsor's employer from April, 2007 - June 2009 was XYZ company, he was employed as data admin. It is also indicated that your sponsor was residing in Pakistan from Sep. 2007 - May. 2009. Please clarify this discrepancy."

Now my company has issued me a letter stated that "I had been working as a Database Admin from April 2007 – June 2009. As an independent sub-contactor, he doesn't require a physical presence in office for providing the services as a database admin. He was working remotely during his presence in Pakistan. He never worked as a permanent employee of XYZ company of Canada."

Yesterday, I sent this letter to CHC, Islamabad. Is this sufficient document or any other doc. will be required?
