Sound familiar?
Working harder than ever. Hearing nothing back.
- 500 applications. Zero interviews.
- “Will you now or in the future require sponsorship?” Yes means rejected. No means trouble later.
- The classmate who skipped lectures just posted “Excited to share…”
- You’ve typed your work history into Workday so many times you know it by heart.
- Your visa clock doesn’t care how hard you’re trying.
- Someone back home asks how it’s going. You say “good.”
- You paid for a job tool once. It renewed while you were still unemployed.
If two of these are you, keep reading. None of it means you’re not good enough.
The idea behind it
It isn’t you. It’s which doors.
A lot of hard work goes to employers who have never sponsored anyone. Each silence starts to feel like a verdict on you. It isn’t. Often the door was never going to open.
Luck is how many doors you knock on. But only real doors count. Five hundred applications to jobs that can’t sponsor you isn’t effort. It’s noise.
The other side of the desk
Recruiters are drowning in bot spam.
A US recruiter described posting a job that couldn’t sponsor visas. By the end of the day: 400 applications, nearly all from people who needed sponsorship, most sent by auto-apply bots. So now many recruiters see “needs a visa” and think “spam”. That hurts every honest applicant, including you.
From a recruiter’s public post on r/recruiting, 2026. One account, not a statistic.
So we built the opposite.
- You press Submit. Every time. Nothing goes out that you haven’t read. Available now
- No-sponsor postings stay hidden. If a job says it won’t sponsor, you won’t see it unless you ask. Available now
- Your real resume, every time. No invented skills or numbers, so every application is one you can defend in an interview. Available now
- A warning before you fill a role that can’t sponsor you. Coming soon
- An application health check. It nudges you away from flooding one company or re-applying too soon. Coming soon
Fewer, better applications, each one clearly from a real person. That’s how you stand out now.
Coming soon: not built yet. We’ll say here when it ships.
Why it’s different
Three things no other tool does together.
01
Official sponsor evidence on every job.
USCIS H-1B data, the UK Home Office sponsor register, the Netherlands IND register and Canada’s LMIA records, with the source and date shown.
02
Answers checked against your real resume.
If your resume doesn’t back a detail up, it’s left out, and you’re told why.
03
You always press Submit.
Knock fills and stops. Your name, your call.
We compared 73 job-search tools in October 2026 and found none that does all three. Tools change, so check for yourself.

Questions
Fair questions
Will it get me a job or a visa?
No tool can promise that, and you should be wary of any that does. Knock helps you spend your effort on employers who have sponsored before, and makes each application faster.
Does it apply for me?
No. It fills the form and stops at Submit. You check and send.
Will recruiters think I’m a bot?
It’s built so they don’t: your real resume, nothing invented, nothing sent by a bot, and no-sponsor jobs hidden.
Is it really free?
Yes. Search, sponsor records, the tracker and 10 filled applications a week cost $0. No card.
Where does my data go?
It stays in your browser, plus your own Google Drive if you choose. Knock has no server holding your resume.
