I don't see anything metioned about the EAD on their website. What can we expect?

It is automatically extended till jan 2 2020. For ur work, i-9 form, you can take USCIS notice and Haiti’s Federal register notice along with old EAD. If u need physical EAD card for driving license, you can apply one but have to pay ~$400 fee.
Basically its same as Haiti’s TPS. Whatever applies to them, applies to Nepali TPS holders. Go to Haiti’s USCIS TPS website, they have all the information. Replace Haiti word with Nepal, aka sh****** countries :):)
