what is best way to get legal us citizenship? I am engineer and want to come us and need citizenship? i can work as engineer? what eligibilities i need?

As an engineer, you can pursue US citizenship through employment-based immigration.

Find a US employer who can sponsor your H-1B or EB-2/EB-3 visa.

After obtaining a Green Card, you'll need to meet residency requirements (typically 5 years) before applying for naturalization.

To be eligible, you'll need a bachelor's degree in engineering, relevant work experience, and proficiency in English.
