How long after the submission of 829, can I sue the Immigration Bureau if the approval is not passed?

The temporary green card is valid for 2 years. Within 90 days before the expiration, the applicant can submit an application in Form I-829 at any time and start to apply for changing the temporary green card into a permanent green card. After successfully submitting the I-829 application, the applicant will receive an I-829 submission receipt provided by the Immigration Bureau, which proves that the applicant's temporary green card is still valid during the I-829 trial and is currently in the application stage for a permanent green card, so he can still legally live in the United States. I-829' s legal identity is valid for 18 months during the probation period. If necessary, I-829 receipt provided by the Immigration Bureau can be used to prove the legal residence of the identity. If I-829 is still under trial during the trial period of I-829, whether it is 18 months or 24 months later, then at this time, if the applicant needs to prove his legal identity, he must personally go to the immigration office and stamp I-55 1 on his passport to show that the legal status of the temporary green card can be extended for another year.
