Returns a published government fee and its effective date. For US (the default), the general filing fee for a USCIS form and filing method. I-129, I-131, and I-907 have no general filing fee: pass category. For I-131, the label this tool uses: a short name of the Appendix B heading, a colon, and the item selector, such as "Reentry Permit: Part 1., Item Number 1." For I-129 and I-907, the category argument says how to name the classification. US covers I-90, I-130, I-140, I-485, I-539, I-765, and N-400, paper and online, and I-129, I-131, and I-907 by category; only some G-1055 categories are covered, and an uncovered one returns no fee. An I-129 amount is the filing fee G-1055 lists for that row. Fees G-1055 lists apart from it are not in the amount. An I-907 amount is the premium processing fee only, not the fee for the form it accompanies. Any other form returns not_found. For GB, the fee for a published Home Office fee category; pass the section heading as category when the name appears in more than one section. For AU, a visa application charge component that Migration Regulations 1994, Schedule 1 states for a visa subclass, from the item's table for any other applicant or its only charge table. Pass the subclass as form, such as "189", and the component as category, such as "Base application charge"; category is required when the subclass has more than one component. 500 and 590 are subclasses whose charge Schedule 1 states in item 1222. Other amounts apply to some applicants; notes names the item and compilation. amount_cents is in the minor unit of currency. filing is "unspecified" when the source states no filing channel. It does not say which fee applies to a case. For a USCIS form's current edition, use check_form_edition. Requires sign-in at https://immigrationlayer.com/login and an active plan. Without a plan it returns subscription_required. Limit: 30 calls per minute per account, shared by all paid tools, then rate_limited. Not legal advice.
