• Soils and Landscapes
• Soils and Land Use

Research and dissertation:

• Students will undertake dissertation research that aligns closely with their advisor's focus and the broader research community.
• Progress is monitored through program milestones, including committee evaluations and dissertation requirements as per Purdue’s doctoral guidelines.

Entry requirements

GRE: While the GRE is recommended, it may be mandatory for applicants to specific academic departments that require it.

English proficiency:

• TOEFL iBT: Required for applicants whose previous education was not conducted in English. Minimum score requirements are set by Purdue and the IESE program, so applicants should consult the latest program guidance during the application process.

Career prospects

Upon completing their degree, international students in the U.S. may be eligible to work, subject to immigration regulations and individual eligibility. Many graduates opt for work authorization through the Optional Practical Training (OPT) program, which allows them to gain practical experience in their field.

• Post-study work authorization: Many graduates pursue OPT after completing their degree.
• Duration: The length of OPT may vary based on the degree level and specific category approved by U.S. Citizenship and Immigration Services (USCIS). Doctoral graduates may qualify for extended OPT under certain conditions.
• Eligibility basics: Generally, maintaining valid F-1 status and good academic standing is required, along with filing the OPT request within specified timeframes.
• Discipline and STEM considerations: Extended OPT is often available for eligible STEM degree programs, contingent on the degree and CIP code meeting STEM OPT criteria.
