In India, it is not necessary to use an Immigration company if you wish to make an application for a visa. You can make a visa application directly, an agency which is generally quite accessible. However, Immigration policies can be complex and difficult to follow, with some rules quite ambiguous. In addition, as Immigration Officers are often managing hundreds of applications at once, it is your responsibility to prove to your Immigration officer that you meet the policy for the visa you are applying for. An Immigration consultant can assess your likelihood of obtaining a visa, help put together a strong application.
