Can I start without translation certification?

Certifications aren't mandatory but can help win projects. ATA certification, university degrees in languages, or relevant experience all add credibility. Focus on building a portfolio first.

Should I disclose that I use AI translation?

It depends on platform and client rules. If explicitly prohibited, don't use AI. If permitted, explain that final quality is guaranteed by human review.

Which language should I start with?

Start with your strongest language. English is the largest market but also most competitive. Having a second language can help you differentiate.
