Can I get scholarships from the Universities like Cambridge, Princeton, and Yale, and mostly Ivy League Universities, for my Masters?

Most definitely, Yes! Getting 100% scholarships at MIT, Stanford, Harvard, or Yale is viable.

Now, I expect that through '100% scholarship', you mean finishing your commencement / under-graduation besides spending from your pocket. There are a few methods by which you can get a 100% scholarship at these Universities:

1. Scholarships
The university will supply you with your education. Once you apply, based on your tutorial profile, the university will determine how many scholarships you will be able to get. 25%, 50%, 75% or from time to time even 100%. Full scholarships are given to students with exceptional song records.

2. Federal Grants
Federal offers are useful economic resources furnished using the Govt. of the USA. Students can practice for national deliveries as well. But, again, based totally on your educational credentials, federal businesses may also determine to provide you with a supply for your education.

3. State Scholarships
Instead of drawing close to the federal govt., you can approach the nation's government. For a grant. A state govt. Has its money been supplied as an aid to the students? Again, the right academic profile is of high importance for full funding.

4. Competitive Scholarships
Competitive scholarships are useful monetary resources furnished by privately funded foundations, organizations, charitable trusts or not-for-profit corporations on the groundwork of merit. The advantage standards might also consist of athletic achievements, educational excellence, or inventive talent.

5. Private Funding
And, of course, you can also get your grad / under-grad funded via private entities. For example, someone you understand who is inclined to help or maybe your ex-employer. In such cases, make sure you are self-sufficient until you graduate. Failing to do so can also cause the university not to receive your admission.

In any case, if your funding is insufficient, you can follow a combination of two or more of these selections to get a 100% scholarship. 

Although, the Ivy League as a team does not award merit, talent, or athletic scholarships to potential students. Instead, Ivy League colleges provide some of the world's strongest need-based monetary useful resource programs.
