N.Y. Limited Liability Company Law § 1305
Except for the provisions of sections eight hundred two and eight hundred nine of this chapter, this chapter shall be applicable to a foreign professional service limited liability company to the extent that the provisions thereof are not in conflict with the provisions of this article. A foreign professional service limited liability company may practice in this state or may consolidate or merge with another limited liability company or other business entity, only if all of the professions practiced by such limited liability company or other business entity could be practiced by a single professional service limited liability company organized in this state; and, further, only if such foreign professional service limited liability company is domiciled in a state the laws of which, at the time of application by such limited liability company under section thirteen hundred six of this article, contain a reciprocal provision under which professional service limited liability companies domiciled in this state may similarly apply for the privilege of doing business in any such state or territory.
