Hi, I like thing to be done right way and few people advised me one company from Leeds to ask for Certificate of Approval for marriage. They are close to where I live so good but do anyone had any experience with them. They specialize in English education as well but I'm more concern about immigration side. Their website http://www.emduk.com/immigration_advice.php
Any feedback?
thanks

You do not apply for Certificate of Approval for Marriage to a company. You have to apply to UKBA for it.
Perhaps you mean that you want to use them as advisors.
I do not have any experience from this company.
I do know of a very good immigration advisor in manchester. If you want, I can give you their details.
