Ladies and Gentlemen:

On behalf of our client, SEI Institutional International Trust (the “Trust”), we are filing, pursuant to Rule 485(b) under the Securities Act of 1933, as amended (the “1933 Act”), Post-Effective Amendment No. 52 and, under the Investment Company Act of 1940, as amended (the “1940 Act”), Amendment No. 53 (the “Amendment”) to the Trust’s Registration Statement on Form N-1A, together with all Exhibits thereto.

This filing is made pursuant to Rule 485(b) under the 1933 Act for the purposes of: (1) designating an effective date; and (2) making other non-material changes.

I hereby certify that the Amendment does not contain disclosure that renders it ineligible to be filed under Rule 485(b).

If you have any questions regarding the Amendment or the foregoing matters, please do not hesitate to contact the undersigned at 215.963.5037.

Sincerely,

/s/ Timothy W. Levin
