After my post-graduation in Canada, I worked as a web designer for Indian partnership firm while living in Canada on post-graduate work permit. I have an offer letter and a contract copy with the firm. I havn't received a monthly salary but received a lumpsum compensation on completion of an assignment. Even I have file a tax return filed for this income. Can this experience be counted for express entry under federal skilled worker category? Are my documents sufficient? What other documents do I need to support this work experience?
