I moved to USA 6 years ago. My native language is Spanish. I would like to practice English because I’m working with Latinos I don’t have a lot of opportunity to practice. I’m taking a class with my tutor but it is just once a week and my friends speak Spanish too. Use "since" with present perfect and a 'point in time" I have lived in the USA since 2015. I have worked at this job since January 2019. Use "for" with present perfect to show DURATION - I have lived here for six years. I have worked for this company for 2 years.
