I've just received this email from a university in the US:

" Hello Ernesto, Thank you for applying to our program! We have received your application and you are a strong candidate. Do you require funding? We are happy to accept you if you do not require funding, but we do not have a GA position for you. Please let me know your needs and if you have any other questions. Sincerely,"

I don't know how to reply them to have any chance to acquire funding; Indeed, scholarships and funds are necessary for my academic life.
