    <summary type="html"><![CDATA[<p>You probably cannot find better investment than tech company stocks for the past
couple of decades. And being part of a unicorn company is the dream job for
domestic or international students: It’s arguably the easiest way for middle
class to become financially independent. However, as the Fed started to raise
interest rates, we witnessed a huge downturn for the tech industry. The once
glamorous programmers suffer from massive layoffs. Investors mourn sharp losses.</p>
<p>As an employee working for a big tech company and worrying deeply about the job
security, I start to wonder the nature of the rapid growth and even faster
collapse of the tech industry. Here, I summarize my findings by reading articles
written by Fu Peng (付鹏), a Chinese economist and Nassim Nicholas Taleb, one of
the greatest “troll”s of our generation.</p>
<h2 id="what-fu-peng-said">What Fu Peng Said</h2>
<p>Fu Peng essentially argues that the tech bubble is a result of excessive capital
derived from unusually low interest rates. And the bubble is further inflated
by, ironically, the slow growth and even the decrease of productivity. Take the
post-pandemic tech bubble as an example. The commence of <a href="https://en.wikipedia.org/wiki/China%E2%80%93United_States_trade_war">China–United States
trade war</a>
signifies the reverse of globalization and hence negatively impacts productivity
of companies from both sides. In the meantime, investors, equipped with the
extreme liquidity as a result of near-zero interest rates after the pandemic,
were eager to spend their free money. Hence, they naturally focused on the
fastest and easiest way to make money – tech companies. After all, all you need
is a good story for the IPO, after which it’s party time. For big tech, their
stock prices are easily lifted by share buybacks. So, it’s still a pretty good
deal.</p>
<p>So, the cycle begins. The management correspondingly shifted their focus from
real innovation (i.e., technology that works for real) to those that can only
make a bombshell. Their business model is no longer the classic: Devise
something that works and make profit out of it. Instead, it’s to lure investors
with easy money. A side-effect is the spoiled programmers. The rapid expansion
of tech companies demands more workforce (pun intended). So, we get ridiculously
high compensation, benefits, and the privilege to work from home.
Correspondingly, what we talk about daily is not technical issues as “hackers”
used to do. Instead, we mostly chat about the stock market, compensation, and
the housing market.</p>
<p>Now, tech companies do not have access to easy money and have to please the
impatient investors with profitability. The moves are straightforward for the
management: cut the expense as well as the projects that won’t produce profit
anytime soon. The good news is that people restart to make real innovation. The
bad news? A new cycle begins sooner or later.</p>
<h2 id="what-taleb-said">What Taleb Said</h2>
<p>While I haven’t got a chance to read Taleb’s understanding (or teasing) of the
tech bubble, the nonlinearity (i.e., winner takes all) he discussed in his book
<a href="https://www.goodreads.com/book/show/38315.Fooled_by_Randomness">“Fooled by
Randomness”</a> is
quite relevant in understanding the nature of the tech industry and hence the
tech bubble. In a nutshell, Taleb attributed the success of
not-the-best-but-dominating products such as the QWERTY keyboard layout and
Microsoft office to <a href="https://en.wikipedia.org/wiki/Path_dependence">path
dependence</a>. In other words,
users simply get used to these technology even though they are far from being
the best.</p>
<p>This reminds me of the notorious business model of Chinese tech companies. They
spend tons of money on a low-quality product just to make the users depend on
it. After that, they raise the price of the product to profit. A character of
this business model is that the competition is not about technology but a game
of capital. Put it differently, programmers are asked to deliver something as
fast as they can and the technology used in it is normally a low priority. A US
counterpart of the business model is Uber and Lyft, who still lose money years
after their IPOs. So, Lyft’s stock price is hit hard by the interest rate hike:
it fails to make its users dependent and thus loses the investment value.</p>]]></summary>

    <title>A Mediocre Researcher's Path to an O-1 Visa</title>
    <link href="https://shaobo.one/blog/2023-02-21-understanding-O1-visa/" />

    <summary type="html"><![CDATA[<p>Since I’ve been dealing with my O-1 petition for a while, I obtained a
reasonable amount of knowledge about O-1 visa. I wrote down my understanding of
it and hope that it could be helpful to future petitioners like me. Note that I
will only talk about the O-1A category as it’s the one which I aimed at. So, O-1
actually refers to O-1A throughout the rest of the article.</p>
<h2 id="disclaimer">Disclaimer</h2>
<p>You should not treat this post as legal advice. Instead, retaining a
professional immigration law firm is highly recommended.</p>
<h2 id="criteria">Criteria</h2>
<p>Let’s cut to the chase. You’re eligible for an O-1 visa if you,</p>

214.2(o)(3)(iii)(B)(8)</a>.</p></li>
</ul>
<h3 id="case-study">Case Study</h3>
<p>I use myself, a mediocre researcher with a computer science Ph.D. degree, as the
case study of the criteria listed above.</p>
<p>The first criterion clearly doesn’t apply to me. As a matter of fact, I would
apply for an EB-1A green card instead had I satisfy it. So, let’s ignore it and
focus on the second one. Let’s examine them one by one.</p>
<h4 id="prizes-and-awards-8-cfr-2142o3iiib1">Prizes and Awards: 8 CFR 214.2(o)(3)(iii)(B)(1)</h4>
<p>It does not apply to me. But you may claim it if you have them.</p>
<h4 id="prestigious-membership-8-cfr-2142o3iiib2">Prestigious Membership: 8 CFR 214.2(o)(3)(iii)(B)(2)</h4>
<p>It does not apply to me. I doubt it will apply to you as well.</p>
<h4 id="media-coverage-8-cfr-2142o3iiib3">Media Coverage: 8 CFR 214.2(o)(3)(iii)(B)(3)</h4>
<p>It does not apply to me. But you can probably claim it if your work has shown up
in media.</p>
<h4 id="judging-the-work-of-others-8-cfr-2142o3iiib4">Judging the Work of Others: 8 CFR 214.2(o)(3)(iii)(B)(4)</h4>
<p>It applies to me because I reviewed a dozen of papers.</p>
<h4 id="contribution-of-major-significance-8-cfr-2142o3iiib5">Contribution of Major Significance: 8 CFR 214.2(o)(3)(iii)(B)(5)</h4>
<p>I claimed it and it’s challenged most frequently by USCIS based on my
observation.</p>
<h4 id="publication-8-cfr-2142o3iiib6">Publication: 8 CFR 214.2(o)(3)(iii)(B)(6)</h4>
<p>It applies to me because I published several papers. Note that you may want to
highlight that CS researchers mostly publish their work at conferences rather
than journals.</p>
<h4 id="essential-employment-8-cfr-2142o3iiib7">Essential Employment: 8 CFR 214.2(o)(3)(iii)(B)(7)</h4>
<p>It does not apply to me. I’m just a regular dude.</p>
<h4 id="high-salary-8-cfr-2142o3iiib8">High Salary: 8 CFR 214.2(o)(3)(iii)(B)(8)</h4>
<p>It does not apply to me. Please refer to the reason above.</p>
<p>In conclusion, a Ph.D. student like me should be eligible for an O-1 visa
provided that he or she can provide convincing evidence for contribution of
major significance.</p>
<h2 id="evidence">Evidence</h2>
<p>Let’s examine what evidence we need for criteria 8 CFR
214.2(o)(3)(iii)(B)(4)-(6).</p>
<h4 id="judging-the-work-of-others-8-cfr-2142o3iiib4-1">Judging the Work of Others: 8 CFR 214.2(o)(3)(iii)(B)(4)</h4>
<p>Evidence for this criterion is self-explanatory. Normally acknowledgement emails
of your peer-review service to journals should suffice. Note that invitation
emails may not count as such evidence because they do not prove that you did the
reviews. If you work on computer science like me, it’s very likely that your
peer reviews are about conference papers instead of journal papers. So, you can
show your acceptance emails as program committee members along with the
screenshots of your reviewed papers’ information. I once served as a PC member
of a conference using EasyChair for paper reviews. I hence submitted a
screenshot of the list of papers I reviewed.</p>
<p>USCIS may question the quality of the papers or the venues where you did the
reviews. I argue that this type of questions are unreasonable because they not
conform to the plain language of the immigration law. However, we petitioners do
not have much leverage and have to respond to this type of questions. Normally,
ranks of the journals and conferences are reasonable objective evidence. You
should be able to find these ranks online. If that’s not possible, letters from
journal editors or conference chairs should work well.</p>
<h4 id="contribution-of-major-significance-8-cfr-2142o3iiib5-1">Contribution of Major Significance: 8 CFR 214.2(o)(3)(iii)(B)(5)</h4>
<p>Proving original scientific, scholarly, or business-related contributions of
major significance in the field is very tricky since the term “major
significance” is pretty vague. I suggest that you talk to your lawyers
thoroughly about your work and adhere to their suggestions. If you are working
on a case yourself, I’d be happy to discuss this category with you and share
more about my thoughts.</p>
<h4 id="publication-8-cfr-2142o3iiib6-1">Publication: 8 CFR 214.2(o)(3)(iii)(B)(6)</h4>
<p>Similar to 8 CFR 214.2(o)(3)(iii)(B)(4), you only need to provide the copies of
your scholarly papers. Normally, the first pages with your name highlighted are
sufficient. Again, USCIS may challenge the significance of your papers. You can
use citation information along with the ranks of the venues where you published
your papers to address the challenge.</p>]]></summary>
