I do not know any MJ congregations that 'require' circumcision at all (except of those ethnically Jewish).

p.s. where do you get your information from?
Why would a Gentile want to become a Messianic Jew if not to follow the OC Mosaic Law as the Jews of today do, including circumcision, and how far back do birth records have to go to establish whether one is of Jewish descent.
I do admit, I am a little confused on the circumcision part
Dr. Arnold Fruchtenbaum - Jews, Gentiles, Christians
Since the Abrahamic Covenant is still very much in effect, these four features also involve the Messianic believer both in his position and function. First of all, Messianic Jews are still Jews, for they, like other Jews, are descendants of Abraham, Isaac, and Jacob. Secondly, the homeland for the Messianic believer is the Land of Israel, and this is where his primary loyalty should be despite his place of residence. Believing Jews are in the Diaspora, but they are also in the Galuth, the Exile. Thirdly, the Gentile relationship to the Jews in the blessing and cursing aspects are as true for Jewish believers as for other Jews. Messianic believers who are blessed or cursed because of their Jewishness will find the blessers blessed and the cursers cursed. Finally, there is the matter of circumcision. Since Jewish believers still fall under the other provisions of the Abrahamic Covenant, they fall under this one as well. It is my conviction that Messianic Jews should have their sons circumcised on the eighth day.
But does not the Book of Galatians argue against the practice of circumcision? Yes and no. Circumcision for Gentiles, circumcision on the basis of the Mosaic Law, and circumcision for justification or sanctification are all wrong. The Book of Galatians condemns circumcision as a means for justification. Except for health and medical reasons, there is never any need or requirement for Gentile circumcision. Furthermore, Messianic believers who circumcise on the basis of the Law of Moses are also wrong, since the Law ended with the Messiah. But this same book clearly states that the Abrahamic Covenant is still very much in effect with all its features, and this includes circumcision. So circumcision on the basis of the Abrahamic Covenant is right and proper, and it is my conviction that it is still very much in effect for Jewish believers. Paul, who taught the Gentiles not to circumcise, did not so teach the Jews; this is clear from Acts 21:17-26, and from Acts 16:1-3 when he had Timothy circumcised. It was not circumcision per se that was ruled out, rather, circumcision on the basis of Mosaic Law.
