> The H-1 is not the H-1B (in the same way that user ID 1030 in your database is not user ID 103) which is probably where the confusion is stemming from.

The H-1B is, under the statute, one of the subcategories within the H-1, and is covered by the same rules except to the extent they are explicitly distinguished. The H-1B1, another subcategory, is explicitly not included in the carve-out of the H-1 from the rule generally prohibiting immigration intent for nonimmigrant visas, which, so the H-1B1 is not, while other H-1s including the H-1B are, dual-intent visas.)

H-1 nonimmigrant visas are the set of visas governed by 8 USC Sec. 1101(a)(15)(h)(i), which included the H-1A [now defunct, formerly Sec 1101(a)(15)(H)(i)(a)], and includes the H-1B [Sec 1101(a)(15)(H)(i)(b)], the H-1B1 [Sec 1101(a)(15)(H)(i)(b1)], and the H-1C [Sec 1101(a)(15)(H)(i)(c)].

The relationship is not the same as ID 1030 to ID 103.

Right, but it's not the H-1. They're named that way because of the category of the code but it's a new visa category that is distinct from the H-1 from the 1950s. The area covered by the H-1 is now in language covered by a different visa.
