Naturalization

Hi,

We are non-euro residing in BE for the past 5 years.  I had recently been to the commune ( Antwerpen Berchem) and they adviced me to apply for Naturalization.

but they asked me to take the help of an experienced professional to fill in the forms.. But i am not sure if i should approach a law firm or if there are other agency that can do these work ( i am willing to pay a fee for it).

Does anyone have similar experience? Can someone help me with a name / tele no. for such firms. Any idea how much they would charge?

Thank you for the help.

Best Regards,

Kim
