The jobs that are the most in-demand for expats in Germany

There currently is a lack of skilled personnel, especially university graduates in the field of IT, engineering, health and research.
(The same applies EU-wide, where the so-called so-called "shortage occupations" in science, mathematics, engineering, health care and IT entile for special considerations for getting a blue card visa.)
However, non-German-speakers are largely limited to very lowly paid professions like harvest helper, cleaner or supermarket shelf stocker. It is very unliklely that a non-EU-citizen gets a visa for such work.

Definitely IT-Software programmers, Cybersecurity. I recieve a lot of requests for these groups. Unfortunately, the big companies "snatch" these experts from other countries. But this is the major deficit we have right now.

What are the types of jobs that are easily accessible to expats in Germany?  Teaching English (or another foreign language) and any job that requires native-speaker levels of another language. These include fields like marketing, customer service, and stuff like that. Often, you can get these jobs just by being a native speaker of whatever language they want, especially if you have a university degree (it can be in almost anything).

What are the ones most in-demand for expats? The above, plus fields like programming (which requires experience but not necessarily German language skills). Fields like engineering, child care and nursing are also in demand and open to hiring expats, but you usually need to speak German to get these jobs.

Which industry and/or jobs have limited workforce? Programming, engineering, child care and nursing have huge worker shortages right now. You need specialised training for these fields, though, and for any health care job, you may need to get your qualifications recognised. You also need to speak German (programming is the exception).

what about pharmaceutical industry especially in drug research and development, is there many jobs in pharma market...kindly provide your opinion

Hallo. My name is Lovely. I am interested to teach in preschool education (kindergarten). I have my degree in Bachelor in Elementary Education major in Preschool Education. In addition, I have 8 years experience in teaching  multi-cultural students. May I ask for your advises for the needed requirements for me to be able to work? Do I have a possibility to teach or be an assistant teacher in Preschools?

Lovely: since there is a shortage of kindergarten teachers., and most kindergartens would like to have an English native speaker, your job chances in Germany are actually very good.
You might just have to take some certification courses if your degree and/or experience is not recognised - and of course you must learn German first, as none of the kids and few of the colleages are likely to understand English well.
Also keep in mind that early educators are not well paid in Germany - you will be able to have a reasonable lifestyle alone, but you cannot provide for a partner or family.
