Consideration for MS if PhD rejected I am a undergraduate student interested in doing my higher studies in USA. I am tempted to apply for PhD program offered by the colleges but I am skeptical of my selection due to high competition. So, I was planning to first do MS from a reputed college and then later do a PhD. This will improve my chances of admit as well.
However, while going through the FAQs of some colleges I came to know that there is a possibility of applying for PhD in a college, and in case the application gets rejected they consider the application for MS as well.
So, I just wanted to know which is a wiser decision? To apply only for MS or to apply for PhD and hope that they select you at least for MS. Also, does the chances of being selected for MS reduce if the applicant follows the latter procedure?
It depends on the discipline and which country/institution you are coming from.  In my experience, most foreign PhD students in US physics programs have master's degrees from their home countries.  Therefore I think PhD admissions committees are expecting a master's degree.

MS programs in the US are usually not selective.  Most international students choose to get the MS in their home country because it is usually much cheaper.
