For couples to adopt, how long do you have to be married?

i know theres a time limit and it really depends on where you adopt from. I know for Korea its 5yr minimum. But what about for a U.S. adoption?For couples to adopt, how long do you have to be married?
In Oregon, it's one year.





It's not about requiring people to be married (single people in Oregon adopt all the time). It's about giving the child a stable home. A single person who has been single and stable for awhile can provide a stable home. After a major life change (marriage, birth, death, etc.), a family can't really provide a stable home. You need time to adjust before adding a new person to your family.For couples to adopt, how long do you have to be married?
Hopefully your country is not so behind the times as to expect couples to be married. In the UK you dont have to be married but you are expected to be in a relationship which is long standing. I would say that the expectation would be that you had been in the partnership for at least 4 years otherwise its just silly as you cant really offer permanence to a child otherwise.
It varies by state and even by agency. My partner and I are not married (because we're gay) and we live in PA. We are adopting right now. The agency we use adopt to gay couples all the time and even to single parents. So many children need homes. They shouldn't put stipulations on who can and cannot adopt. As long as their FBI check and clearances are okay, They should be allowed to raise a child.
No idea on the US, but in the UK there's no requirement for the aparent/s to be married. Heck, you can be single and still adopt in the UK.
There shouldn't be a limit within the US. Single people adopt all the time.
