Change of Status(COS) H1 to H4

Was on H1B, I was laid off on April 20, 2025. Now, need to change my status back to H-4 (without EAD)as soon as possible.

I’ve heard that the I-539 application can be filed online instead of paper-based, but I’m unsure which route is best.

In the online application, there’s a question: “What is your current nonimmigrant status?” The closest available option to H-1B is “H-1B1 Specialty Occupation”, but H-1B1 is specifically for Chile & Singapore.

Should I select this option and proceed, or is it safer to file a paper application instead, given I only have 10 days left?

If anyone has genuine insights or personal experience, please share! Any guidance would be greatly appreciated.
