Do you think lagging behind in English language is a serious handicap for professionals and skilled personnel to advance their career in a foreign country?

Speaking one language gets you onto the racetrack, but two will knock down half the hurdles. Communicating in a foreign tongue can be the most exhilarating experience. And it will probably help you get a job too.

Yes of sure , I think so.

English is the world language, the dominant in commerce and media. The language cruises at the era of globalization, technology and is arguably at its most dominant position in its history. But is it a blessing or curse for the nonnative people who speak it as a second language, rather than a first language should take in consideration learning English language efficiently to speak fluently.From my viewSpeaking English language fluently gets you onto the racetrack, but speaking fluently as natives will knock down half the hurdles because communicating in a foreign tongue can be the most exciting experience and it will probably help professionals to advance their career in foreign countries as well it could help others to get their dream job too.

English language is considered a global language for communication so command on it is a plus point even if one is serving in a non English speaking country. 

People who are enthusiastic to make progress in their career without boundaries must learn English language at an expert level.

Thanks for the call agreed with the answers the rest ، the English language is very important for communication and business

First, don't panic. Then, don't lose either faith or hope. A person who knows the meaning of "lag behind" and forms his question the way you do is perfect. I disagree with some ideas mentioned above. English is advantageous of course, but if you are a genius and your work is not based on it, it will be just fine. Mastering English, which is a global means of  communication, plus handling computers will add to you. English is the language of science and technology and you need it to keep up to date. You can do it: you can learn faster and better. Good luck. Have faith.
