How to verify authenticity of Employment letter

I am so sick with employment letters. If they want you, they can do all.

For the moderator, please consider the posts with this topic. (ie remove straightaway)

If you are good as an employee they will take you. (they want you, not the reverse)

If (I am bit older (so not relevant for me )) I would go for a job I expect a possible employer to pay for flights.hotels and taxi. )  (and they did)

Bottom line they should ask for YOU and pay for you.

Paying for anything is a big, big red flag,

Interesting quite from this thread

@Cheryl In Turkey, there is no document called a Foreign Worker's Certificate per se. If you are a foreign national looking for work in Turkey, you have two options. Firstly, if you already have a residence permit, you can apply directly to companies within Turkey. Alternatively, you can apply for a work visa, which can only be obtained by visiting a local Turkish embassy in your home country or a country that allows, for example, Germany or Georgia, without a local residence permit. There are Foreign Workers' invitational letters with barcodes that list the company, its legal credentials, and its address and are signed and stamped in blue ink. Anyone can email the local Turkish embassy and ask if a job offer is legit.

Bottom line I do not care, if your potential employer wants you, he can arrange.
