Will I Be Able to Work?
You and your spouse and children may not accept employment. However, you may apply for practical training after you complete your studies. If approved, you will be allowed to have one month of practical training for every four months of study you have completed. You will be limited to six months total practical training time.

You should submit USCIS Form 538 (Certification By Designated School Official) to the USCIS. Your school official should certify on USCIS Form I-538 that 1) the proposed employment is for the purpose of practical training; 2) the training will be related to your studies; and 3) you can not receive the same type of training in your country of residence. You must also submit USCIS Form I-765 (Application for Employment Authorization), and your I-20 ID, signed by the designated school official (DSO). You should send your application to USCIS no more than 60 days before your student status expires and no later than 30 days after your studies are completed. For more information, please see the rules about practical training at 8 CFR § 214.2(m). You may also wish to discuss practical training with the appropriate officials at your school.
