If you are looking to bring friends from China to the US or you are applying for a status change or visa yourself, you may require supporting documents in Mandarin to be translated into English by a certified translator so that such documents can be accepted by USCIS. So, what do you have to do now? Apparently, ask around for a translation company which could help you. The trick is to find the one able to provide you with professional services within your timeframe and budget, of course.
The rule of thumb when looking for a certified translation company is to ask for a quote and compare the cost and professionalism of work with other companies on the market. You might be surprised that prices can vary significantly from one company to another.
