Thank you for the information.
I am willing to admit that I am wrong about something, but this still appears fraudulent.
The reason is:
1. There is no such thing as a tax clearance code or certificate for loans in Nigeria. None. You are being asked to pay up front 1800 dollars.
2. The email proxy to add to contacts in the heading you provided is: [email protected] a gmail account.
3. Letters similar to yours have gone out from the ECC. Simply that a person has been listed by the EFCC, assuming your domain verification was really the EFCC's domain, (I can not tell from the information appearing in your transmission). If you give me the domain that you verified, I would be better able to tell.
4. He gets upset when you say you go to the IRS.
Note that these scammers are highly sophisticated and set up clone websites, and email proxy's to emulate official organizations.
Think of this. What reason would I have of leading you astray. What possible motivation could I have, for 7.50 cents, (my share of the question fee), to lead you down the wrong path.
The Nigerian government itself is corrupt. This is the most corrupt nation on the planet. Nigeria alone, is responsible for more than 30% of all Internet and electronic scams and fraud, according to the U.S. Justice Department. The corruption of the government in Nigeria, is cited in a U.S. Department of Commerce report as a major barrier to international trade with Nigeria. (it is so pervasive, that it is referred to as a trade barrier)
So let's assume this is the one legitimate lender, and he is asking for an 1800 dollar fee to get the loan, and is calling it a tax clearance code or certificate. So you are a hard person to convince. I understand that people do not like to think they would be frauded by a friend or someone they met. I understand you are desperate for this loan.
I once paid an expedite fee, for example, directly to the pocket of the Minister of Interior in Mexico, to get a business visa for a superstar sales person to attend a sales conference in Cabo Mexico. I was told by my attorney, they could approve the Indian Citizen for his visas, but it would require an expedite fee. I know Mexico does not have expedite fees. So I asked the attorney: so is this fee going directly to the government or into the pocket of the minister of interior? The response was, "sometimes, mr. J, that is how business is done in Mexico. I paid the 1,000. BUT, I knew it was fraud. The cost of the person not going to the meeting was far great than the 1,000. Not attending could have cost us several million.
IN your case, the difference is, that there is no guarantee you will get your loan.
At this point, I would still say it is a scam.
If you do not have the money to pay, then you will need to borrow that. The following link will be a good place to borrow 1800. http://www.prosper.com
You will need to contact the person you are getting the money from and ask them to guide you in getting the certificate and pay what ever you need.
Some people have to learn the hard way. I have spent 4 hours on this question. that is less than 2 dollars an hour. So it is not about the money. It is about doing service. So friend, please do not accept this answer. It is free to you. You will be losing too much other money. I consider this my probono public service announcement.
Good luck. AND if you get the loan, please let me know.
