Naturally you will be able to use the Paraliminals if you are able to understand English. Even a person who is not quite fluent in hearing English will find they will have success with Paraliminals. The might need to use them a bit more than a fluent or native speaker.
Using Paraliminals if it's not your native language is traveling in a country were you only know a bit of the language. You don't go up to native and say 'What are the interesting sites to see around here?" The person will start talking and using words you don't understand.
You can go up to a native and ask for directions. Because you know what you want it's faster knowing where you are going to go.
So for a person who has English as a second language it is important that they have a purpose for listening. Know what you intend to gain from the listening experience. This is important for everyone using the and even Paraliminal but even more so for people with English as a second langauge.
