CAN ANY HELP ME TO CHECK OR VERIFIED THAT I AM RECEIVED ALL OF ABOVE LETTER IS FAKE OR REAL
Pretty much guaranteed it's fake.
If they are offering to pay for your flight or accommodation or food - then it's fake.
If they are asking you for money - then it is fake.
If you got the job easily - it is fake.
If they are telling you there is urgency in applying - it is fake.
