1. Do some research about what kind of programs are offered in your state/immediate area: in person programs are typically better than online only schools. Many traditional schools offer hybrid programs and evenin classes for adult learners. Location will be a main factor. One of the best indicators for success is that it should be easy for you to get to class, that way you are more likely to stick with the program.
2. Many private "technical" colleges have a reputation of being diploma mills and you may have trouble getting hired with a degree you paid a lot of money for. I personally would stick to public colleges/universities, and then look at established private institutions. Look for cost/timeframe and what kind of certification you will be getting. Sometimes, especially since you already have a degree, getting a certificate is more helpful than getting another degree. Sometimes you can get so many credits transferred in that you could get another degree in the timeframe it takes you to get a certificate. You will need to meet with an advisor
3. yes, see above. Don't fall for a diploma mill. If it sounds too good to be true, it probably is!
4. This will depend upon the school. Some schools do credential evaluations in house, others ask that you use a service such as WES or AACRAO or a local service they contract with. They are very particular, do not spend the money on an eval before you know what is required. You can however go ahead and contact your former university to inquire how you can receive official transcripts... that can be quite a hassle and take some time in some countries.
5. Fill out a FAFSA (google it) and speak to the school's financial aid department.
6. Most likely yes. You should check your states licensing requirements and options, sometimes there are differences, sometimes they just use different names in different states.
Good luck!
