Can I file for unemployment even if I’m not sure I qualify?

I work for a major fast food chain and my location is set to be remodeled in 2 months. We can work at other locations while ours is closed, but I’m worried I won’t get enough hours because I can’t build up a huge savings to keep me afloat when the store closes (they’re estimating a few weeks).

I know it takes a while to process it, so what happens when I receive unemployment but I ended up not qualifying for/needing it?
