To apply for Chartered Engineer (CEng) status in the UK while living in the U.S., it's essential to register with a relevant professional body like IMechE. A direct application is required, and applicants must demonstrate sufficient experience in all competency areas outlined in the UK-SPEC. Contacting the Engineering Council is advisable, especially for those overseas, as there may be additional requirements. Accreditation issues could arise depending on the origin of your degrees, but they can be navigated with proper qualifications and experience. Most institutions provide detailed guidance and support for international applicants.
