The short answer is no, you do not need an attorney to renew your green card. However, you may have problems if you have stayed in India for too long (more than 6 months, 2 1/2 years of last 5 years), and shown indication that you have relinquished right to re-enter USA, without an application for Parole, where an explanation of your absence showing non-intent to renounce legal residency is attached. If you wish to discuss it further, with prospect of the help of an attorney, by all means call or e-mail me to set up a telephonic consultation. I can call back through Skype for international conferencing.
