I think Georgia and North Carolina all have easier bar exams.
FYI — North Carolina is not anymore open to LLM applicants since 2005.
Please find below some information found on p.26-29 of this NCBE's document about bars eligibility to LL.M. applicants:
http://www.ncbex.org/pdfviewer/?file=%2Fassets%2FBarAdmissionGuide%2FNCBE-CompGuide-2019.pdf#page=25 California: Applicant must have graduated and be eligible to take the admission exam in his/her foreign country and obtain an additional year of law study in certain courses at an ABA-approved or California-accredited law school in order to qualify to take the California Bar Exam.
Georgia: A lawyer educated at a law school outside of the United States may meet the educational requirements and be eligible to take the exam if the foreign-educated lawyer graduated from a foreign law school that meets the requirements of the Rules; is authorized to practice law in the foreign jurisdiction; and has been awarded, by an ABA-approved law school, an LL.M. that meets the Curricular Criteria for LL.M. Program for the Practice of Law in the United States adopted by the Board of Bar Examiners.
Kentucky: Applicant must still submit to education evaluation but additional degree has bearing on Board decision.
Maine: Applicant’s total education must be found to be substantially equivalent.
Massachusetts: Not automatically, but depends on content (course of study) as well as other facts.
New Hampshire: Not automatically. Applicant must meet other requirements for foreign law school graduates.
New York: In most cases, but there are other factors.
Tennessee: Applicant must prove that undergraduate and law school education are the equivalent of that required by an applicant who attended an ABA-accredited law school or Tennessee law school approved by the Board of Law Examiners. In addition to the LL.M., the applicant must be licensed in the country in which the applicant was educated and have been engaged in the active practice of law for 5 of the 8 years immediately preceding the application.
Texas: An applicant with an initial law degree from a foreign law school not based on English common law must, in part, be authorized to practice law and have a qualifying LL.M. degree. An applicant with an initial law degree from a foreign law school based on English common law must, in part, either have a qualifying LL.M. degree or satisfy a 3-year practice requirement.
Vermont: Graduates of foreign law schools that do not provide the equivalent of an education at an ABA-approved law school can cure that deficiency by obtaining an LL.M. degree at an ABA-approved law school, provided the LL.M. degree meets certain requirements pertaining to the amount and type of credit hours.
Washington: An LL.M. degree for the practice of law must meet certain requirements.
Wisconsin: Applicant must meet and show proof of the following requirements: (a) that the law school was approved in that foreign jurisdiction, (b) that the LL.M. program meets specific minimum requirements pertaining to total semester hours of credit, minutes of instruction, and duration of program, and (c) that the LL.M. program consists of a certain number of semester hours of specified courses. The LL.M. program must be located at an ABA-approved law school and be completed within 24 months of enrollment.
Additionally, another way to be admitted in Washington is to pass another US bar and then transfer your bar license to Washington.
To choose a bar you should ask yourself:
1.
"Which US bar is the more relevant for my practice area?" and
2.
"Which US bar is the more relevant with the country where I plan to practice?"1. I am not an expert in international law, but I am pretty sure that Washington and maybe NY should be the more relevant bars in that field. But it will probably also depend on your sub-practice area in international law. Expl: If your sub-practice area is IP/IT conflicts in international law it could be more focus on California law, while if your sub-practice area is environmental law it could be more focus on Colorado law and Vermont law.
2. To my understanding, for countries of South America it's an asset to get a bar from NY, Washington, California and maybe also Florida (because Miami is an important business hub for Central and South America's countries).
