Guide to OPT and H-1B Visas After Studying in the US: The Complete Path from Internship to Full-Time Work

Foreword

"Teacher, can I stay in the U.S. to work after graduation?"

I have answered this question countless times every year.

Staying in the U.S. for employment after graduation is the goal of many international students. But here's the problem: many people don't know what OPT is, how to apply for H-1B, or how to transition from student status to work status.

Today I'll help you figure all these out.
