The answer to your question depends on the precise nature of your claim. You should speak to an experienced employment lawyer as soon as possible to see if you have any time left. Many of us, myself included, will provide a free consultation. Whatever you do, don't delay as you probably don't have a lot of time left to file.

I agree with Josh, it will depend on the nature of your claim. As a brief aside, however, some of these statutes are very short. For example, the one dealing with unfair labor practices under the National Labor Relations Act is 6 months. Under Title VII, you have to file a charge with the EEOC withing 180 days, but may be 300 days depending on other considerations.
