The United States is a popular destination for migrants for many different reasons such as employment, marriage, family reunions and to gain refugee status. However, the government has strict quotas every year for limiting the number of migrants in certain categories. Sometimes preferential treatment is given to migrants seeking to work in certain occupations that are short of U.S. workers, while there are other categories such as skilled migrants who may have an annual cap that is typically filled well before the middle of each year.
Whatever visa category you intend to use when entering the U.S. you will still need to get all your key documents translated into English, if they are written in a language other than English. There are no hard and fast rules for using a skilled translator as long as the person who was hired to complete the job is prepared to sign a statement agreeing that the translation is accurate. For a document like a birth certificate it has to be a USCIS birth certificate translation which means it is acceptable as part of your application. As soon as your USCIS birth certificate translation has been approved you will be getting closer to entering the U.S. as a new stage in your life.
You can search the internet to find a suitable translator for the pair of languages. Some will be individual freelancers and others will be companies who source a suitable freelancer on your behalf. You will have to send a scanned photocopy of your birth certificate to the translator who will complete the translation and return it to you by the date you have agreed on.
The translator must be prepared to provide his or her name, signature, present address and the date the translation was completed and of course a statement saying the translation is accurate. This will now be considered to be a USCIS birth certificate translation and when you have gathered together all your other documents you will need to send the photocopy of your birth certificate plus the translation in order to complete the process.
