For now, UI lasts for 6 months, and any additional extensions will only last until the end of this month. Previously, when unemployment was at its peak, it was possible to draw for 99 weeks, or about 1.9 years.
There is a 50/50 chance that the temporary extensions will be reinstated for another period, it is not for certain at all, since the last extensions were barely passed, and only 6 months after the previous extensions had expired. Additionally, unemployment has gone down. As unemployment has dropped, the extensions have become increasingly unpopular.
