The latest available case-by-case Immigrant Court records show that immigration cases that were completed in the first four months of FY 2021 took nearly twice as long from beginning to end as cases completed in the first four months of FY 2020. Cases that were completed bet­ween the beginning of October 2020 and the end of January 2021 took, on average, 859 days compared to 436 days over the same period a year before. The duration was calculated as the number of days bet­ween the date the Notice to Appear was issued to the date of completion as recorded in the Immigration Court's records.
