These organizations don’t have offices in the USA raising funds for them. Donations to foreign entities are not tax deductible.
What exist in the USA are fundraising organizations such as “American Friends of Yeshiva Aleph, Bais, Gimmel” which are 501(c)(3) non profit charitable organizations. Donations to the 501s are tax deductible.
RY Haim Yankel of the above Yeshiva is listed for a candidate with that attribution, not as President of the 501.
More more than 40 years I have supported Kiryat Sanz Laniado Hospital by donating to the American Friends of the same, If I contributed directly to the hospital I would lose the tax deduction. So, I take advantage of the tax laws and increase my planned donation by the tax bracket I am in.
