As an international student, is is a good idea to apply for PhD in U.S. to get financial aid and after 1 year change it to Masters?

I'm an international student and I'm studying computer science. As you now, it is really hard to get full financial support for masters in the U.S. but it would be really easier for PhD. Assuming my preference is definitely studying masters and considering my need for full financial support, is it a logical and practical decision with the hope of changing it to a masters in near future?

P.S: Please be realistic and avoid giving a "no answer" just because it is not a regular action.
