H 1b can I add new applicants for the second and third rounds of lottery?

The H 1B lottery has 65,000 regular caps every year, and another 20,000 places are provided to applicants who have obtained master's degrees or above in the United States. So 85,000 people draw lots in H 1B every year.

The new policy of H 1B changed the lottery order. Immigration will

_ First, 65,000 applicants with full academic qualifications were selected from the whole talent pool.

_ Draw another 20,000 places from the remaining losers with master's degree or above.

This change is more beneficial to applicants with a master's degree or above in the United States! When the bill was published, official website and the National Security Bureau also specifically mentioned that this change was a great benefit to the master and doctor. It is estimated that the winning rate of applicants with master's degree or above will increase, and the number of places will increase by 5340!

Does this policy really improve the winning rate of applicants with master's degree or above? Let's take a look at the following probability analysis and 20 19 H 1B lottery data!

Calculation of H 1B lottery probability

The probability of winning the undergraduate degree = the probability of winning the first round of lottery =(H- 1B conventional cap of 65,000 places)/total number of applicants.

Probability of obtaining a master's degree or above = (winning probability in the first round of lottery)+(losing probability in the first round of lottery) * (losing probability in the first round of lottery is put into the second round of master's exemption)

Note: This calculation method is calculated by GOH 1B according to your own understanding, and is for reference only. This calculation method does not deduct the 6,800 reserved places in Singapore and Chile. If all 6800 reserved places are used up, the actual winning proportion will be slightly smaller than the probability calculated above.
