The term “trade” should be “construed broadly” and “liberally.” Trade means the exchange, purchase, or sale of goods and/or services. Goods are tangible commodities or merchandise having intrinsic value. Services are economic activities whose outputs are other than tangible goods. Such service activities include, but are not limited to, banking, insurance, transportation, communications and data processing, advertising, accounting, design and engineering, management consulting, tourism, and technology transfer. The term “commerce” has been defined as “the exchange of goods, productions, or property of any kind; especially, exchange on a large scale, as between states or nations.” INS has considered certain refugee relief agencies and non-profit organizations to be engaged in development of foreign trade and commerce. Evidence of being “engaged in the development of foreign trade and commerce” could include, for example: a list of foreign clients with their contact information, a specific description of all projects, contracts, and properties which the company is pursuing, a description of the funding of the work to be performed abroad, evidence that the employing firm or corporation is permitted to conduct business abroad, copies of all contracts, proposals, requests for proposals, or requests for bids for work to be performed abroad, and copies of financial statements and the applicants tax returns and transcripts.
