First of, have faith and trust yourself. You can do it. Actually, I think accounting is an easy field to get a volunteering into. I belong to a different field and it is quite hard to get volunteering services in it. You can apply for internships (paid or unpaid), which are better than volunteering. Try recruiters in your area and go through them for internships, they will have a whole lot better ideas and ways to get you an internship. Companies pay them for these kinds of services. But, be sure to have an attractive resume before you go to them. Include all details in your resume, exageratte (sp) things (a bit), write about every technical/professional terms you know even though you only have learned about them in text books. Google something like "accounting recruiters" or just "recruiters" and choose ones in your area. Set up an appointment and go meet them personally, do not just submit your resume online.

Which part of the country do you live in??? There are some Indian accounting firms in some parts of the country and they will most probably given you an internship or volunteer chances. Or, just apply to individual companies directly, but I think going through recruiters would be faster and easier.

All the best to you. Write in this thread if you need more suggestions and pls o write which state you're in.
