You will work on drug abuse and addiction research. If you are looking for similar funded opportunities in the United States, explore fully funded scholarships in USA for international students.

Who Can Apply?

NIDA fellowships are open to non‑US citizens. You must hold a doctoral degree (PhD, MD, or equivalent). You should have experience in drug abuse research. You must be living and working outside the United States at the time of application. You also need good English skills.

Three Types of NIDA Fellowships

1. DISCA and USDISCA Fellowships for Senior Researchers

These awards are for senior researchers with at least seven years of experience beyond postdoctoral training. You must have a strong publication record. The fellowship covers a research exchange visit of at least four weeks. You receive a one‑time payment of up to $8,000 for living expenses and round‑trip airfare. You are responsible for your visa and health insurance.

To apply, send your application electronically to ip@nida.nih.gov. There is no fixed deadline – applications are accepted year‑round.

2. Hubert H. Humphrey Drug Use and Addiction Research Fellowship

This is a 10‑month, non‑degree program for mid‑career professionals. You will study at a US university and complete a six‑week research placement with a NIDA‑supported scientist. The fellowship covers tuition, living allowance, book allowance, round‑trip airfare, health insurance, and professional development activities.

You need a doctoral degree (master’s with extensive experience may be considered). You must have a mid‑career position in a university, government ministry, NGO, or healthcare organization. Contact your local Fulbright Commission or US Embassy to apply.

3. INVEST Fellowships for Postdoctoral Training

These are 12‑month fellowships for early‑career researchers. You will train under a NIDA‑funded mentor at a US institution. There are three sub‑types:

• INVEST Drug Use and Addiction Research Fellowship – Open to any biomedical or behavioral science field.

• INVEST/Clinical Trials Network (CTN) Fellowship – For research on clinical trials, intervention methods, or HIV/AIDS prevention.

• INVEST Prevention Fellowship – Focuses on prevention science.

Benefits include a living stipend, health insurance allowance, professional development funds, and air travel. You may apply to renew once.

Eligibility: You must have a doctoral degree and at least two years of postdoctoral experience (recommended). Your home institution must provide a letter assuring you a position after the fellowship. You must be a citizen or permanent resident of a country other than the USA.

How to Apply for INVEST Fellowships

First, write a brief research proposal. Identify a NIDA‑funded mentor in the US. Use the NIH RePORTER database or ask the NIDA International Program for help. Once you have a mentor, complete the application form together. Your mentor must provide a mentor statement and a letter from their institution confirming they can sponsor your J‑1 visa. You also need two reference letters, your doctoral degree certificate, and a letter of assurance from your home employer.

Submit everything by email to ip@nida.nih.gov.
