Why Did You Decide To Become An Immigration Attorney?

I became an immigration attorney as I wanted to help people who come to this country to secure a better future for themselves and their family. As an immigrant myself I can relate to my clients and I understand why this is so important to them. – Sandra Dorsthorst
