I would assume you need a social security number to qualify for any government assistance
Legally the ER cannot turn away anyone and have to accept you even if you cannot pay.
You can go to an ER regardless. If it's an emergency, they will see her. But yes she needs that info for billing or it will cause major issues later for her.
she can apply for emergency access only but im not sure if that will cover but you can def try. you dont need social to apply for that
Lizbeth where does she apply for that at ?
