Lost EAD card - Do I need a new I-20 for replacement? What’s the process?

Hi, I recently lost my EAD card (OPT), and I’m trying to understand the process to request a replacement. My EAD was already approved and issued earlier.

My DSO advised me to check with USCIS, so I wanted to ask here if anyone has gone through this recently and could share any guidance. I'd really appreciate it.

• Do I need to request a new I-20 from my DSO, or can I use my previously approved I-20 with OPT authorization to apply for a replacement EAD?
• What supporting documents are required for a replacement application?
• How long does it typically take to receive the replacement card?
• Can I continue working while waiting for the replacement if I already have valid OPT authorization?
