Working with an Immigration Attorney
Immigrants should take an active role in the immigration process. An attorney can help guide an immigrant through the procedure and make any required legal arguments, but the immigrants must supply the facts. This typically means going through files and getting copies of all the necessary documents to the attorney's office. The most successful cases are the ones where immigrants work with their attorneys to compile the necessary information and make the proper filings in a timely fashion. This section contains resources and tips to help immigrants assist their attorneys as they make their case before the USCIS.
