No.  “EB2” simply refers to the applicant category.  The resultant green card is the same as other green cards.

There are two alternative methods for qualifying for an EB2 green card:  have a relevant advanced degree or an exceptional ability.

• Advanced degree. You may be eligible for an EB2 green card visa if you meet all three of the following criteria:
  1. You are a member of the professions holding an advanced degree or its equivalent.
  2. The job you apply for must require an advanced degree
  3. You possess such a degree or its equivalent (a baccalaureate degree plus 5 years progressive work experience in the field).
• Exceptional ability.  You must be able to demonstrate both of the following:
  1. You have exceptional ability in the sciences, arts, or business
  2. In the future that exceptional ability will substantially benefit the U.S. economy, cultural or educational interests, or welfare.

No, not every individual with an advanced degree will qualify.  EB2 applicants must demonstrate that their occupation is a profession.  The term “profession” is defined as any occupation for which a U.S. baccalaureate degree or its foreign equivalent is the minimum requirement for entry into the occupation.  “Professional” occupations include (but are not limited to) architects, engineers, lawyers, physicians, surgeons, and teachers in elementary or secondary schools, colleges, academics, or seminaries

Exceptional ability means a degree of expertise significantly above that ordinarily encountered in the sciences, arts, or business.  EB2 applicants who claim to have Exceptional Ability must meet three out of the following seven criteria:

• Official academic record showing that you have a degree, diploma, certificate, or similar award from a college, university, school, or other institution of learning relating to your area of exceptional ability
• Letters documenting at least 10 years of full-time experience in your occupation
• A license to practice your profession or certification for your profession or occupation
• Evidence that you have commanded a salary or other remuneration for services that demonstrates your exceptional ability
• Membership in a professional association(s)
• Recognition for your achievements and significant contributions to your industry or field by your peers, government entities, professional or business organizations
• Other comparable evidence of eligibility is also acceptable.

Entrepreneurs should discuss which element (ie, national economy, cultural or educational interest, or welfare of the United States) their entrepreneurial enterprise is claimed to benefit.  For example, the educational interests of the United States may be met by an entrepreneurial enterprise that establishes tutoring instruction learning centers throughout the United States.

As another example, the entrepreneur could demonstrate that at least one aspect of the welfare of the United States will be “substantially” better off were the entrepreneurial enterprise to be located in the United States.  It should be noted that the term “welfare” as used by the statute is a broad concept and could refer to any number of areas. 

USCIS offers premium processing for EB2 green cards.  This expedited processing can reduce the processing time to 15 days.  However, if USCIS requests additional evidentiary documentation, the process can be extended by an additional 15 days after receipt of the requested documents.  Afterwards EB2 green card applicants who are overseas will then schedule an interview at their US consulate.
