I have placed a freeze on my credit file.  Will that be an issue?
If you have placed a freeze on your credit file, you must life or remove it at each credit bureau before you can continue with this process.  Your application will not be processed if you have a security freeze.
Can I apply for a PLUS Loan online?
You can, and as with anything else on the web, you just go to the website and log in to start and then you would start the demo.
