Equitable tolling is a principle of law that allows individuals to file a law suit, claim or immigration application after the standard statute of limitation is expired. In common law, in order to file an immigration application such as an adjustment of status application mentioned above, it must be done within a time frame recognized by the law. If you file a case or claim beyond that time frame, you will lose your right to file such claim or case. However, in criminal or civil cases, such as removal proceedings, you can still file a case beyond the statute of limitation via what is called equitable tolling. In essence, equitable tolling comes in place when you have been removed from the immigration judge and later need to adjust your status. Generally, in order to adjust your status, you will have to file a motion of reopen within 90 days from when the immigration judge's final decision of your removal proceeding case. If you decide to get married with a US citizen after the 90 days requirement and wish to adjust your status, the 90 days period will be equitably tolled or extended so you can timely file your motion to reopen. If you believe that you may have new evidence or extraordinary circumstances sufficient to support a motion to reopen in your previous immigration proceedings, you may want to consider consulting with an immigration attorney experienced in preparing, submitting and subsequently litigating successful motions to reopen in Immigration Court.
