At the first two steps of this project:
1) scan all WAC-02 cases at BCIS Case Status Online to obtain all I485 case numbers
2) scan I485 case status regularly to grasp the BCIS CSC activity
a lot of inquiries are required,
however, the BCIS Case Status Online seems to limit about 1,000 inquiries per IP address and per day.
To avoid this limitation, there are two methods as follows.
1) use proxy servers
Using n proxies, I can inquire n x 1000 cases per day.
A proxy server must tunnel HTTPS request and response,
but only a few proxy servers support this feature,
and many of them seem not to be stable enough,
so still my inquiries are limited.
2) contributors to scan
If m people scan everyday for n days, we can inquire m x n x 1000 cases even if using no proxy, and stably.
I provide a Java program for this purpose, and there are another tools available such as off-patience's script for Excel.
If you are interested in some specific date, I encourage you to scan by yourself.
If you send me the result of your scan,
I will incorporate it into my database, and I will share my data with contributors.
Some people had been asking me to scan a specific date like:
"please scan WAC-02-XXX series, thanks"
however, I can not do that for the above technical limitation.
Instead of asking me or somebody,
you can do that by yourself.
You can find the information in this thread.
I will never response this kind of request at all.
