United States immigration law is complex. Trying to sort through all the rules and regulations can be a complicated and frustrating experience. Because of this, many people make mistakes when trying to navigate immigration issues on their own. This book discusses some of the more common mistakes that I see as an immigration lawyer. This book is not intended as, and does not provide, legal advice. It does aim, however, to provide helpful information that may assist people in understanding the immigration mistakes that could derail their immigration case. It also provides useful information on what an immigration lawyer can do to help solve immigration problems and what you should consider before hiring an immigration lawyer.
