Possibly. It seems you're referring to the following Federal Regulations in 8 CFR § 214.2(h)(4)(iii), in particular paragraph (h)(4)(iii)(D)(5), which describes one way to meet the requirements if you don't have a Bachelor's degree or higher:
A determination by the Service that the equivalent of the degree required by the specialty occupation has been acquired through a combination of education, specialized training, and/or work experience in areas related to the specialty and that the alien has achieved recognition of expertise in the specialty occupation as a result of such training and experience. For purposes of determining equivalency to a baccalaureate degree in the specialty, three years of specialized training and/or work experience must be demonstrated for each year of college-level training the alien lacks. [...]
So yes, you must demonstrate three years of work experience or specialized training for each year of your degree that you lack. However, that's not the only requirement; you have to demonstrate more than just the number of years.
You need to demonstrate that your experience meets certain requirements:
It must be clearly demonstrated that the alien's training and/or work experience included the theoretical and practical application of specialized knowledge required by the specialty occupation; that the alien's experience was gained while working with peers, supervisors, or subordinates who have a degree or its equivalent in the specialty occupation;
And finally, you need to show documentation that demonstrates recognition of your expertise in your field:
and that the alien has recognition of expertise in the specialty evidenced by at least one type of documentation such as:
(i) Recognition of expertise in the specialty occupation by at least two recognized authorities in the same specialty occupation;
(ii) Membership in a recognized foreign or United States association or society in the specialty occupation;
(iii) Published material by or about the alien in professional publications, trade journals, books, or major newspapers;
(iv) Licensure or registration to practice the specialty occupation in a foreign country; or
(v) Achievements which a recognized authority has determined to be significant contributions to the field of the specialty occupation.
