what does it mean priority date is current
Priority date Priority date is a United States immigration concept â€“ it is the date when a principal applicant first reveals his intent of immigration to the US government. For family-sponsored applicants, the priority date is the date an immigration petition, filed on behalf of him or her, is received by the United States Citizenship and Immigration Services (USCIS). For employment-based immigration beneficiaries, the priority date is the date an immigration petition is filed at USCIS, under categories where a labor certification is not required, or when the United States Department of Labor receives a labor certification application, under categories where a labor certification is required. In all cases, the priority dates are not established until USCIS approves the immigration petition. The date establishes one's place in the queue for a family-sponsored or employment-based or permanent residency permit (also known as "green card") application.
Real-time operating system A key characteristic of an RTOS is the level of its consistency concerning the amount of time it takes to accept and complete an application's task; the variability is jitter.[1] A hard real-time operating system has less jitter than a soft real-time operating system. The chief design goal is not high throughput, but rather a guarantee of a soft or hard performance category. An RTOS that can usually or generally meet a deadline is a soft real-time OS, but if it can meet a deadline deterministically it is a hard real-time OS.[2]
