I've talked to a few Syrian Jews and they don't seem to accept converts at all even if it was 3 or 4 generations ago, if you ask me, I'd say they really view everything from a racial perspective. My fathers family was hardcore in protecting the Cohen lineage believing he should only marry another Cohen which I think is extreme as it is but the Syrian Jews seem to take it a step further. What are your experiences with them?
http://isteve.blogspot.com/2007/11/syrian-jews.html “Never accept a convert or a child born of a convert,” Kassin told me by phone, summarizing the message. “Push them away with strong hands from our community. Why? Because we don’t want gentile characteristics.” ...
“It’s really a matter of statistics,” [Rabbi Elie Abadie ] explained to me. “Except for the Orthodox, the American Jewish community is shrinking, disappearing. In two generations, most of their grandchildren won’t even be Jews. But our community is growing. We have large families, five or six children. And only a tiny fraction of our kids leave. The Edict is what makes that true.”
Abadie and Kassin agree that the vast majority of SY youth abide by the strictures of the Edict. “Ninety-nine percent accept it,” Kassin said. “When someone doesn’t, it’s painful, but it’s better to lose a kid here and there and save the community. Families get sick over it, sure, but that’s how it is.”
Kassin knows this from personal experience. His sister Anna ran off with a gentile. Naturally it was a great scandal in the community, but the chief rabbi didn’t bend the rules for his daughter. “We cut her off,” Jakie Kassin told me. “We didn’t see her for 25 years. But we never stopped hoping she’d come back. Finally, after all these years, she made contact. We told her she was welcome to come back, but not with her husband or kids. She’s not here yet, but we do talk on the telephone.”
In addition to the strictures imposed by the Edict in instances of proposed intermarriage, any outsider who wants to marry into a Syrian family — even a fellow Jew — is subject to thorough genealogical investigation. That means producing proof, going back at least three generations and attested to by an Orthodox rabbi, of the candidates’ kosher bona fides. This disqualifies the vast majority of American Jews, who have no such proof. “We won’t take them — not even if we go back three or four generations — if someone in their line was married by a Reform or Conservative rabbi, because they don’t perform marriages according to Orthodox law,” Kassin said. Even Orthodox candidates are screened, to make sure there are no gentiles or converts lurking in the family tree. ...
The force of the Edict is lasting: the children of people who have been excluded under the terms of the Edict are themselves declared ineligible to marry into the community.

My personal opinion is that it goes quite extreme for the Syrian Jewish community to reject their grandchildren if the person had someone in their family that converted 3-4 generations ago. I don't think i'd want to marry someone that picky though.
