If a school desperately needs a German teacher and i have no green card to reside in the States...?
Answer:
You certainly can ask them.
There are several ways to work there legally as a teacher: as a J-1 exchange visitor, as an H-1 professional, or they can even sponsor you for an employment-based immigrant visa. Explore all of those options here:

I would think you qualify for either a Student or Work Visa. Having a Sponsor makes the paperwork go smoother. Be cautious about what web pages you seek info from. I just tried to go directly to the info for you. There are too many lawyer websites that look entirely legit, official and they want big fees for information downloads.
To seek, free, official information, keep in mind the US gov't has changed its name from "Immigration & Naturalization" -- INS to "Dept. of Homeland Security".
I had a tough time clicking around, looking for what I know is free information. They had it under "Visit the US".
Since you said you are from "outside the US", If you are illegal in the US.(Overstaying your visa, or something), it's very difficult for you to get sponsors that include J-visa.(Teacher exchange.)
Most of teachers are hire by school boards of their county. if you have county you like to work, check their web site. Most of case, school board lists all they need include teachers. in many case, they ask experience of 2 years or more.
If you are looking into J-visa (It gives you 3 years maximum in US) go to http://exchanges.state.gov/education/jex...
go to Private sector and click on teacher. You will find all the organization which is license by US department to sponsor J-visa program.
Good luck
Some great answers here. Contact that school and apply and ask if they will act as a sponsor on your behalf. Then ask or learn if they will class/educate you in taking the state test so that you are qualified to teach and gain tenure. Some counties or public schools hire many overseas teachers as their population grows in leaps and bounds. I would as well suggest if that school you want now will not sponsor you, then find a school system that will and you at lest will be employed and a certified school teacher, then you can at your leisure select perhaps a better opportunity.
