Jeremiah Shea is really a very responsible and professional Canadian immigration consultant. Based on your unique situation, he will make the best plan for you. In my case, after I got my IELTS I tried to apply for Express Entry on my own. As time passed and I did not receive an Invitation to Apply I knew I needed professional help.
When I found Mr. Shea he said he would do his best to help me, but could never guarantee visa issuance. Mr. Shea enabled me to understand what was required in a very clear and organized way. He helped me improve my score by 84 points in four months, resulting in an Invitation to Apply!
