Report of Independent Registered Public Accounting
Firm


To the Shareholders of the Funds and Board of
Trustees
SEI Institutional International Trust:

In planning and performing our audits of the
financial statements of SEI Institutional
International Trust, comprised of International
Equity Fund, Emerging Markets Equity Fund,
International Fixed Income Fund, and Emerging
Markets Debt Fund, (collectively, the Funds), as of
and for the year ended September 30, 2021, in
accordance with the standards of the Public Company
Accounting Oversight Board (United States), we
considered the Funds internal control over financial
reporting, including controls over safeguarding
securities, as a basis for designing our auditing
procedures for the purpose of expressing our opinion
on the Funds financial statements and to comply with
the requirements of Form N-CEN, but not for the
purpose of expressing an opinion on the
effectiveness of the Funds internal control over
financial reporting. Accordingly, we express no such
opinion.
Management of the Funds is responsible for
establishing and maintaining effective internal
control over financial reporting. In fulfilling this
responsibility, estimates and judgments by
management are required to assess the expected
benefits and related costs of controls. A companys
internal control over financial reporting is a
process designed to provide reasonable assurance
regarding the reliability of financial reporting and
the preparation of financial statements for external
purposes in accordance with generally accepted
accounting principles. A companys internal control
over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of
records that, in reasonable detail, accurately and
fairly reflect the transactions and dispositions of
the assets of the company; (2) provide reasonable
assurance that transactions are recorded as
necessary to permit preparation of financial
statements in accordance with generally accepted
accounting principles, and that receipts and
expenditures of the company are being made only in
accordance with authorizations of management and
trustees of the company; and (3) provide reasonable
assurance regarding prevention or timely detection
of unauthorized acquisition, use, or disposition of
the companys assets that could have a material
effect on the financial statements.
Because of its inherent limitations, internal
control over financial reporting may not prevent or
detect misstatements. Also, projections of any
evaluation of effectiveness to future periods are
subject to the risk that controls may become
inadequate because of changes in conditions, or that
the degree of compliance with the policies or
procedures may deteriorate.
A deficiency in internal control over financial
reporting exists when the design or operation of a
control does not allow management or employees, in
the normal course of performing their assigned
functions, to prevent or detect misstatements on a
timely basis. A material weakness is a deficiency,
or a combination of deficiencies, in internal
control over financial reporting, such that there is
a reasonable possibility that a material
misstatement of the Funds annual or interim
financial statements will not be prevented or
detected on a timely basis.
Our consideration of the Funds internal control over
financial reporting was for the limited purpose
described in the first paragraph and would not
necessarily disclose all deficiencies in internal
control that might be material weaknesses under
standards established by the Public Company
Accounting Oversight Board (United States). However,
we noted no deficiencies in the Funds internal
control over financial reporting and its operation,
including controls over safeguarding securities that
we consider to be a material weakness as defined
above as of September 30, 2021.
This report is intended solely for the information
and use of management and the Board of Trustees of
the Funds and the Securities and Exchange Commission
and is not intended to be and should not be used by
anyone other than these specified parties.
