Replying to [Arkady]:
If your seller is interested in discounting his 60 days' DA (usance) LC in Germany, I presume that he'll do so at his own bank, or a bank to which the LC (that your bank in US is going to open) is restricted, or the bank in Germany that confirms the LC, or a bank that is willing to extend this discounting facility.
Hence I am wondering, why your question! Why do you need to know about a bank in Germany?
