April 1st usually marks the first day when USCIS accepts H-1B cap subject petitions. Once sufficient petitions are received and accepted for processing by USCIS, cap-subject H-1B visas will be unavailable until the following year. For employers seeking to hire foreign nationals to fill certain specialty occupation positions, this means that for the remainder of the year, they have to find alternative means to fulfill their need. Some alternative non-immigrant work visas include the, L1A for manager/executive transferees; L1B for specialized knowledge transferees; O1 for extraordinary ability workers; TN for Canadian and Mexican professional workers; E1 for the treaty-traders and E2 for treaty investors. A labor certification (PERM) can also be an alternative path towards directly obtaining lawful permanent residency or pursued in conjunction with a non-immigrant visa.
