Not legally possible, but would be a beautiful thing if it could happen.
no.
yes,you can legally adopt the minor.You will need to see a lawyer for free advice consultation.There may be a few requirements depending on what state you live in,but most are about the same when it comes to that.
To get a legal guardian, a family to live with and to be supported by his parents. Being abandoned does not mean you are on your own or emancipated or that a judge will emancipate you.
Minors are not allowed to adopt.
This is not up to you. A minor can not do that. You need you parents top give up their rights and the social workers take over. If someone wants to adopt you they have to speak to your parents first.
First of all at 20 they are no longer a minor. They became an adult at 18. So, you don't adopt an adult.
An undocumented immigrant will not be able to file in a passport application on behalf of his/her child. Only a US citizen can do this. However a passport application for a minor child will require the parental consent from both its parents and also the proof of the citizenship status of the parents. Identification documents of both the parents should also be submitted along with the application.
No, a minor cannot adopt another minor. And most jurisdictions don't allow adoption under the age of 21.
Depends on how old the minor is and where you live. If she is old enough to be given parental consent you can.
Generally no; you must be self sufficient with ample life experience to properly nurture a child in order to be allowed to adopt. speculation: in some jurisdictions it may be possible to do a step parent adoption at 17.
If its your baby then shame on you for doing her with a minor! that should be on your concious! but also i believe you should adopt the baby if you ready to be a father.
only if they (the Mexican immigrant) is also a minor, and you both get your parents permission (if you are under the legal marriage age in your state). and although its not relevant, you should make sure that they are legally here before you marry, or your husband/wife may and up getting deported...and that would REALLY suck
