When you have been offered a job in the U.S. and your native language is not English you will be required to get a diploma translation to English before the United States Immigration and Citizenship Service (USCIS) will approve your request to take up employment.
There are strict requirements to enter the U.S. and many other countries when it comes to providing proof of your qualifications. Immigrants are only allowed to use their qualifications to obtain employment in many countries if these qualifications have equal status to the qualifications of the country they wish to work in. If you were to provide your original diploma certificate in your native language, the official who looks at your application will not be able to understand the document so therefore will not be able to make a decision.
You may be bilingual and think that you can do the diploma translation to English yourself,however, USCIS does not allow this. You will need to get an approved translation company to undertake the translation. You must hire a capable translator who is required to write a signed statement stating that the translation is an accurate diploma translation to English. Any mistakes which are detected in the translation could lead to delays in getting the appropriate visa approved. If the translator has failed to note the words in a watermark or seal, the translation may not get approved as an accurate diploma translation to English. Make sure you hire the right translation company do translate your most important documents.
