No, don't hire a lawyer for sponsorship file. You do not need their help at all on a family sponsorship file, there is not much lawyer can do to help you on the file. All they will do is submit the application, in any case you will be the one filling out all the family information because you know better than the lawyer. If you absolutely require help in filling out the application form, seek help from friend or family or this forum. Lawyer will rip you off the money, there is no work worth $5000-7000 to be done on filing application. If your sponsorship file is rejected for some reason, then only to appeal the case you may need a lawyer help. I WOULD STRONGLY SUGGEST NOT TO GO TO SEE A LAWYER, THE APPLICATION FILING IS A VERY EASY PROCESS NOT WORTH SPENDING THOUSANDS OF DOLLARS ON LAWYERS, WHO DOES VERY LITTLE, BUT CHARGES TONS OF MONEY TO RIP OFF THE CLIENTS.
