I filed a Writ of Mandamus myself without an attorney, using ChatGPT to help me prepare the filing. My lawsuit was not about speeding up a green card application; it was because USCIS had been taking an unreasonably long time to adjudicate my I-360 SIJS petition. About 5–7 days after the mandamus was filed, USCIS approved my I-360. Shortly after that, an attorney from the U.S. Attorney’s Office contacted me and asked me to dismiss the federal court case since USCIS had already taken action on the petition. In my case, the mandamus was very effective.
