Debbie Said:

does community college in american offer international student program?

We Answered:

Community colleges in the US do admit international students. Often, you'd pay the "out of state" rate on tuition, rather than the lower rate offered to residents of that state. But you are absolutely welcome to attend.

Community colleges in some regions have more international students than in others. For example, the ccs in California, Texas, NYC, Boston, Philly, Florida, and other areas attractive to foreign immigrants tend to have a lot of foreign students.

Martha Said:

how can do know whether certain university offer international student program through internet?

We Answered:

Almost all universities in the USA accept international students who meet their requirements, including passing the TOEFL. The universities usually do not offer special programs for the international students. To inquire about a specific university, you may send an email to its admissions office. It may take several weeks before you receive a reply.

Of course, you should start your quest by entering the name of the university (only) into google.com. Then navigate the university's official website, which in the USA probably has a URL which ends in .edu to try to find information pertaining to international students.
