What is the way to adopt in the future, while applying, to put the name of the person I will adopt in the future on the forms?

[ROCIOLIVELY]

You need to be the sponsor. BUT if you husband is willing to he can be the co-signer (so combined income will be considered) and sign up to provide for your parents and brother for the next 20 years. (after and if they are approved to become PRs)
AND NOT just your parents need to pass medical, your brother needs to pass medical as well. And as far as we can tell from the information given, it's unlikely that he will pass.

As others have suggested and I saw the I have also answered your previous post... you are asking similar questions again. It doesn't matter if you use the term caregiver, dependent or adopt to be your own, he is not part of your immigration application.

Thank you very much, I have a clearer picture now, there are no alternatives for now. Yes, I tried to ask several questions to look for possibilities, because I love my little brother, but I will be patient with time. Thank you very much, the best thing is to acquire information to avoid mistakes. Thank you very much!! Blessings.
