🏛️ UK Visa Assistant - Fine-tuned Mistral-7B Instruct

This is a fine-tuned version of the Mistral 7B Instruct model, specifically tailored for answering questions and assisting with processes related to UK visas, immigration categories, documentation requirements, and official guidance.

🧠 Model Summary

• Base model: Mistral-7B-Instruct-v0.3
• Fine-tuning method: LoRA
• Domain: UK visa & immigration policy
• Intended use: Assisting users, lawyers, and support agents in navigating UK visa rules and processes
• Trained with: A curated corpus of UK visa documentation, official Home Office guidance, and common user queries

📚 Use Cases

• Answering questions like:
  • "What are the requirements for a Skilled Worker visa?"
  • "Can I switch from a Student Visa to a Start-up Visa in the UK?"
  • "What documents do I need for a spouse visa?"
• Assisting in form-filling guidance
• Clarifying rule changes or processing times

🚀 How to Use

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("lironui/UK_Visa_Assistant")
tokenizer = AutoTokenizer.from_pretrained("lironui/UK_Visa_Assistant")

prompt = "What are the English language requirements for a UK Skilled Worker visa?"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=1024)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

📝 Note: For best results, format prompts using Mistral's instruct style (e.g., <s>[INST] your question [/INST])

📝 Dataset

The model was trained on a custom dataset containing:

• Home Office visa guidance PDFs
• Official UK government immigration website content
• Annotated user questions and responses from visa forums (anonymized)
• Policy update logs from gov.uk

⚠️ Limitations

• May not reflect very recent policy updates (check gov.uk for latest info)
• Should not be relied on for legal advice
• Performance on non-UK immigration topics is untested
