English is not the only way to get certified.
As one of the largest certification providers, CompTIA is an internationally ExamTopicsFree recognized certification provider. It is often believed that non-native English speakers simply need to take stock and learn English to get certified. IT professionals around the world take CompTIA tests, but many do so after arriving in an English-speaking country.
If English is not your first language, remember to check if there are easier language options. Some tests offer up to seven language options and unfortunately other tests are only in English. One of the benefits of CompTIA Network+ is that the N0-00 can be taken in Japanese, German, and English.
If you get certified now, you will (maybe) no longer need it.
Certificates that would last a lifetime or at least ten years before an IT professional ExamTopicsFree had to come back and renew. The certificate is valid for years from the date of issue. But with ongoing training, you can renew your certification with little effort. So you won't have to retake the test as long as you are taking the necessary steps to meet them.
