Consulates repeatedly warn against the use of "immigration consultants" due to the high rate of frauds & scams. NEVER use any immigration consultant. Use of any "consultant" is grounds for visa denial, or revocation with deportation/mandatory departure, and permanent bar to entry for fraud.
If you cannot read a country's immigration website, follow directions & fill out some forms on your own, you don't qualify for immigration anyway. If you do not meet all requirements to qualify for some type of visa or immigration, no immigration consultant can help you. An immigration attorney would give you accurate legal advice, but cannot "make" you qualified when you are not.
Do not waste your time or money looking for an immigration consultant.
