And what is required for a single parent adoption in US?

In about 5 years i will be ready to adopt a child. I’m single and (being a man), most adoption agencies will shun the idea of a single man wanting to adopt. I would like to know if anyone who reads this can direct me to a website of an agency who will allow single parent adoption…or if you have any other suggestions as to how i can have children please include. I have babysit-ted many children over the years and realized that it is my only wish to have kids.I want to adopt a newborn or young baby under 1. (in about five years, so there’s time) Please give me advice, it will be greatly appreciated.

Say a woman does not get married and conceives a child with a man. Can that child have the father’s last name, or will it have to legally bare it’s mother’s last name?
Can a minor be adopted with having it’s last name changed to it’s parents/guardians?
How common is single parent adoption? (As in a single non-married person adopting a kid.)

I’m writing a story and it’s recently dawned on me that a character’s last name may become an issue.
Bad typos: I meant without having to change it’s last name to accomidate it’s gaurdians/parents.
Not that the current answers are bad, in fact they helped a lot, but I wanted to add a little bit to help out the last question.
He’s adopted in the state of Maryland at the age of 14. I’m not sure if this helps, but I thought it wouldn’t hurt to add.

Well I’m having some trouble and for my essay I need an attention grabber to start out with, but i don’t know what to use as one with the topic of single parent adoption. Any ideas?
And for people who are all for it, can you tell me why??
Thanks!
I also need help for ideas on the call-to-action, where you kind of go out and do something about it

Apparently China no longer allows single parent adoption as of April 2007. So, what are some countries that are more commonly chosen by adoptive parents that allow single women to adopt?
Yeah, I’m aware of America’s adoption laws. I was thinking more about intercountry adoption. I’m sorry, but every website I’ve been too has a list of waiting kids who are either drug babies with the related mental and physical disabilities, kids who suffered from fetal alcohol syndrome, or children that in some way are developementally disabled. I greatly appreciate that there are people out there willing to adopt these children but I am not one of those people. I do work and it wouldn’t make sense to me to adopt a disabled child who would need the care and attention of a mother who could stay home all day with him or her without worrying about going to work.
