Maybe because the US Rabbanim are up to their eyebrows trying to hold down the front here?
I delayed my halachic geirus for several years in order to find the right beis din whose gerus would be guaranteed to be accepted in EY, because I had already had a non-halachic conversion, and wanted to make sure I never had to do it again. I conduct myself properly and adhere to the mitzvos in a yeshivish community. Every time this subject comes up, I get nervous and wonder if this is the issue that will lead to my geirus being questioned. At this point, I’m just waiting for Moshiach and leaving the Israeli politics to the Israelis. Maybe that’s how the US Rabbonim feel also.
