US visa scheduling site not working? What each error means

What should you do first, whatever the error?

Stop clicking. Nearly every message on this page gets worse with rapid retries and better with a pause. Note the exact wording (screenshot it), close extra tabs, wait at least a few minutes, then sign in once through the normal home page. If the same message returns for days at the same step, contact official portal support.

The messages, one by one

"You have exceeded the limit for viewing this page"

What it means: the portal caps how many times you can load the appointment calendar in a day, and you hit the cap. It's a view limit, not a ban, and it doesn't touch your application. The exact daily number isn't published; guides for the previous portal described roughly a dozen calendar actions per day, and applicants report the same flavor of limit on the current site.

What to try: nothing today. Sign out and come back the next day — community guidance for the older portal put the reset around midnight US Eastern time, but treat any reset time as folklore until your own account confirms it.

Don't: keep poking at the calendar from the same account. Applicants on the older portal reported that pushing past the view limit escalated into multi-day freezes. One day of patience is the cheap option.

"Access limitation … prohibited conduct"

The full message applicants quote: "Access limitation. Your attempt to view the calendar section was blocked due to violation of prohibited conduct clause of terms and conditions of use of appointment system."

What it means: the portal believes something non-human touched the calendar from your browser — reports tie this screen, which began appearing around July 2024, to browser extensions and plugins that interact with the scheduling site. The portal's terms prohibit automated access, and this is the enforcement screen.

What to try: remove or disable any extension that touches usvisascheduling.com, then stay off the site for at least 24 hours before signing in again — through a clean browser profile or incognito window, as a human, by hand. That is also the only way anyone should ever use this portal: the embassy has canceled appointments linked to automated booking, so a blocked session is the smallpenalty.

Don't: hop VPNs or try workarounds to get back in faster. The block is the site telling you what it saw; change what it saw.

"Sorry, you have been blocked"

What it means: this one isn't the scheduling system at all — it's the site's security layer (the page usually mentions a Ray ID) refusing your connection before you reach the portal. Common triggers reported: VPNs, corporate or campus networks, and connections it flags as suspicious.

What to try: turn off any VPN, leave the office network, and try a normal home or mobile connection. Clearing cookies and cache, or a different browser, also features in applicant fixes. If it persists everywhere, contact official support and include the Ray ID shown on the block page — that's what it's for.

Don't: hammer the same blocked connection. The block is per-connection and per-pattern; repeating the pattern repeats the block.

PSE0501

What it means (community-inferred): applicants see PSE0501 while the portal is loading available appointment days, switching locations, or moving through payment and slot selection. The consistent reading across reports: the portal couldn't complete your request. It is not evidence of hidden slots, and not proof that no slots exist — it's the system failing to answer.

What to try: wait a few minutes, then sign in fresh through the home page and let each page load fully before clicking on. If PSE0501 returns for days at the exact same step, it may be account-specific — that's a support case, with screenshots.

Don't: re-submit payments to get past it. Fees are nonrefundable; see the payment section below.

SGA10, SGA15, SGA20

What it means (community-inferred): SGA-coded errors show up in the consular calendar, most often during the two-step OFC-then-interview booking. Applicant reports associate SGA10 with the temporary hold on your OFC selection expiring before the consular step was completed. The usual advice: return to the portal home page and start again from the OFC step.

What to try: if you were mid-booking, this is the "window lapsed" scenario — we wrote a full guide for it:OFC booked but no consular slots. Check your appointments page and email to see what was actually saved before redoing anything.

Don't: assume you're booked because the OFC leg went through. Until both appointments show in your account, the booking isn't finished.

OTP and sign-in failures

What it means: the portal signs you in with a one-time code, and the code step fails more than any other — the code never arrives, arrives late, or is rejected as invalid. Usually this is delivery and timing, not your account: codes expire fast, and a late code is a dead code.

What to try: request one code and wait for it — requesting several in a row invalidates earlier ones. Check spam. Enter the newest code promptly. Use the email address your profile was created with (for accounts migrated from the old CGI portal, that's the old CGI email). A mainstream browser without aggressive privacy extensions helps.

Don't: fire off five code requests in two minutes. You'll chase your own invalidated codes in a loop. This section is general sign-in guidance; the portal doesn't document its OTP rules.

Session timeouts and surprise sign-outs

What it means: the portal ends idle or long-running sessions, and a timed-out session fails in odd ways — buttons that do nothing, half-loaded calendars, or an error page where a date list should be. We couldn't pin down one official message string; the symptom is the message.

What to try: sign out fully, close the tab, sign back in, and do the thing you came to do promptly rather than leaving the tab open for hours. One tab, one session — a second tab on the same account is a classic source of weirdness.

Don't: leave a booking half-done while you "quickly check" something elsewhere. If you're inside the OFC-to-consular window, the clock is running — see the OFC guide.

Payment and MRV receipt errors

What it means: messages like "The receipt number entered is not a complete MRV fee payment" or an "invalid receipt number" mean the portal can't match your fee payment to your profile — a sync or data problem, not necessarily a missing payment.

What to try: first check your account for an MRV receipt number before doing anything else. If a payment failed with a system error, official guidance is firm: do not pay again — visa fees are nonrefundable, and double payments are hard to unwind. Collect your payment proof and raise it with official support.

Don't: make a second payment to "fix" the first, and don't create a second profile to try again — mismatched duplicate profiles are a known source of exactly these errors.

"You may only reschedule 1 more time" and reschedule-limit warnings

What it means: these aren't malfunctions — they're the portal telling you the rules. The portal allows only a limited number of reschedules; after that, booking again means paying the visa fee again. The warning appears when you're about to spend, or have spent, your allowance. The limit has changed more than once, so trust the number on your screen (more in the OFC guide).

What to try: read the warning literally before clicking continue. Reschedule only to a date you'll keep.

Don't: burn the last reschedule chasing a marginally better date. The message means exactly what it says.

When does an error actually mean a lockout?

Most errors here are moments, not lockouts. The view-limit message is a one-day cap. The "Access limitation" screen reportedly clears after 24+ hours once extensions are gone. A security block ends when the connection stops looking suspicious. True multi-day freezes are mostly reported after someone kept forcing a limited account — the lockout usually follows the retries, not the error.

Is it an error, or a ghost slot?

If dates appeared and then vanished without any error message, that's usually not a malfunction at all — it's a ghost slot, a date the calendar shows but the booking step never honors. Errors are the portal telling you to stop; ghosts are the portal showing you something that isn't there. We wrote the full explainer:What is a ghost slot?

Fewer visits, fewer errors

Look back at the list: the limit, the block, the lockout — they all come from visiting and refreshing a lot, which is exactly what the portal punishes and exactly what slot anxiety makes you do.

The calmer loop: let GetMyVisa's verified alerts (dates still listed after our confirmation window) tell you when real dates have opened, check the slot history to see what's been appearing for your consulate, and sign in when there's something worth signing in for. Fewer visits, fewer errors, and your limits are intact on the day it matters.
