Please keep this in mind:

• You do not need to hire an immigration representative to apply for a visa or for Canadian citizenship. Immigration representatives do not have special connections with Canadian government officials and cannot guarantee you a visa.  Only authorized officers at Canadian embassies, high commissions and consulates can decide whether or not to issue a visa.
• Don’t be tempted into using false documents as this will result in the refusal of your application.  Beware of internet scams and false websites.
• Processing fees are the same at all Canadian visa offices around the world. Fees in local currency are based on official exchange rates and correspond with the amount in Canadian dollars.
• Canadian visa offices will never ask you to deposit money into an individual’s personal bank accounts or to transfer money through a specific private money transfer company.
• If you have questions, contact CIC or the visa office responsible for your area.

Who can legally represent you if you choose to hire an immigration representative?   Immigration consultants, lawyers, and other representatives give immigration advice and help to visa applicants, usually for a fee.
